It is a tool for updating checksum files in vendor directories. After modifying files, e.g. when patching sources for building packages.
If you already in the package catalog. Run the following command to update
checksum for file nix/src/net/mod.rs:
cargo-vendor-checksum --files-in-vendor-dir nix/src/net/mod.rs
Vendor directory could be specified via vendor flag:
cargo-vendor-checksum --vendor $PWD/hyperfine/vendor -f nix/src/net/mod.rs
Checksum for alt files could be updated via command:
cargo-vendor-checksum --all
This command could take a lot of time to complete.
