Unable to run segmenter code in wasm

[riajain0412]

Hi,

I was trying to run segmenter code on wasm. Below is the code in my rust file:

use wasm_bindgen::prelude::*;
use icu_segmenter::LineSegmenter

#[wasm_bindgen]
extern {
    pub fn alert(s: &str);
}

#[wasm_bindgen]
pub fn greet() {
    let segmenter =
    LineSegmenter::try_new_unstable(&icu_testdata::unstable())
        .expect("Data exists");

let breakpoints: Vec<usize> =
    segmenter.segment_str("Hello World").collect();
assert_eq!(&breakpoints, &[6, 11]);
}

Code in my Cargo.toml file:

[package]
name = "hello-wasm"
version = "0.1.0"
authors = ["Ria Jain <[email protected]>"]
description = "A sample project with wasm-pack"
license = "MIT/Apache-2.0"
repository = "https://github.com/yourgithubusername/hello-wasm"
edition = "2018"

[lib]
crate-type = ["cdylib"]

[dependencies]
icu = "1.0.0"
wasm-bindgen = "0.2"
icu_segmenter = "0.7.0"
icu_testdata = "1.0.0"

First I run icu4x-datagen command to build data blob and then I run cargo run, it says no LineSegmenter in the root

Please enable the icu_segmenter feature on icu_testdata.

still getting the same error

Your code looks fine, so long as you make sure it compiles (no syntax errors). icu_segmenter::LineSegmenter is an unconditional export.

[riajain0412]

This error is coming in wasm-pack command. I'm unable to get that what am I doing wrong.
And also, do I have to push my code in git?

[sffc]

It sounds like your issue is likely not ICU4X-specific.

I always encourage building a Rust-only package first, before adding in complexity like wasm-pack.

I was trying to implement segmenter in Mac also but was facing this issue there as well.
