+ + + +

+ version + + +

+ +
+ +

The module implements version management following semantic versioning principles with custom adaptations for +Arista EOS and CloudVision Portal (CVP) software versioning schemes.

+
+
description + str + +
+

A basic description of this class.

+
+
+ + +

Examples:

+ 
# Basic SemVer usage:
+>>> version = SemVer(major=4, minor=23, patch=3)
+'4.23.3'
+
+# EOS version handling:
+>>> eos = EosVersion.from_str('4.23.3M')
+>>> eos.branch
+'4.23'
+
+# CVP version handling:
+>>> cvp = CvpVersion.from_str('2024.1.0')
+>>> str(cvp)
+
+ +

The module enforces version format validation through regular expressions and provides +comprehensive comparison operations (==, !=, <, <=, >, >=) between versions.

+ + +
+ Note: +
    +
  • EOS versions follow the format: ..[M|F]
    • +
  • CVP versions follow the format: ..
    • +
+
+ + + + + + + +
+ + + + + + + + +
+ + + +

+ CvpVersion + + +

+ + +
+

+ Bases: SemVer

+ + +

A CloudVision Portal Version class that inherits from SemVer.

+

This class implements version management for CloudVision Portal (CVP) versions +following a modified semantic versioning pattern where: +- major version represents the year (e.g. 2024) +- minor version represents feature releases +- patch version represents bug fixes

+ + +

Examples:

+ 
>>> version = CvpVersion(2024, 1, 0)
+>>> str(version)
+'2024.1.0'
+

+ + +
+

+ Bases: SemVer

+ + +

+ + +

Examples:

+ 
>>> version = EosVersion(major=4, minor=21, patch=1, rtype="M")
+>>> print(version)
+EosVersion(major=4, minor=21, patch=1, rtype='M', other=None)
+>>> version = EosVersion.from_str('4.32.1F')

+ SemVer + + +

+ + +
+

+ Bases: BaseModel

+ + +

A class to represent a Semantic Version (SemVer) based on pydanntic.

+

This class provides methods to parse, compare, and manipulate semantic versions. +It supports standard semantic versioning with optional release type and additional version information.

+ + +

+ 
>>> version = SemVer(major=4, minor=23, patch=3, rtype="M")
+>>> str(version)
+'4.23.3M'
+
+ 
>>> version2 = SemVer.from_str('4.24.1F')
+>>> version2.branch
+'4.24'
+
+ 
>>> version < version2
+True

+
from_str(semver: str) -> SemVer
+
+ +
+ +

+

This method parses a semantic version string or branch name into a SemVer object. +It supports both standard semver format (x.y.z) and branch format.

+ + +

Parameters:

+ + + + + + + + + + + + + + + + + +
NameTypeDescriptionDefault
+ semver + + str + +
+

The version string to parse. Can be either a semantic version +string (e.g., “1.2.3”) or a branch format.

+ 		+ required +
+ + +

Returns:

+ + + + + + + + + + + + + +
TypeDescription
+ SemVer + +
+

A SemVer object representing the parsed version. +Returns an empty SemVer object if parsing fails.

+
+
+ + +

Examples:

+ 
>>> SemVer.from_str("1.2.3")
+SemVer(major=1, minor=2, patch=3)
+>>> SemVer.from_str("branch-1.2.3")

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.
