A parser for finding hashtags in strings. For example parsing Rust is #awesome gives you awesome and its location within the string.

The goal of this crate is to match Instagram's parsing of hashtags. So if you find strings that aren't parsed correctly please open an issue 😃

extern crate hashtag;

use hashtag::Hashtag;

pub fn main() {
    let tags: Vec<Hashtag> = Hashtag::parse("#rust is #awesome");
    println!("{:?}", tags);
    // => [
    //     Hashtag { text: "rust", start: 0, end: 4 },
    //     Hashtag { text: "awesome", start: 9, end: 16 }
    // ]
}

I have written a fairly simple benchmarking.

Run it with:

cargo build --release && ./target/release/benchmark

./bin has some scripts that you might find helpful.

• bin/watch uses cargo watch to run tests and other things when you save a file.
• bin/publish used to publish the current version to <crates.io>.
