Change stream

A Stream that only emits if the value is different.

Important

• The stream item is stored in the struct by Cloning so the stream Item must implement Clone
• The comparison for the items is done via an equality check so the Item must implement PartialEq with itself

Example usage

• Add to your Cargo.toml file toml [dependencies] change_stream = "0.1.0"
• Import the StreamChanged trait and call .changed() on an existing stream: ```rust use change_stream::StreamChanged; use futures::{stream::iter, StreamExt};

[tokio::main]

async fn main() { let a = iter([1, 1, 2]);

a.changed().for_each(|a| async move {
    dbg!(a); //will only emit 1 and 2
}).await;

} ```
