# copypasta
copypasta is a (rust-clipboard)[https://github.com/aweinstock314/rust-clipboard] fork, adding support for the Wayland clipboard.
rust-clipboard is a cross-platform library for getting and setting the contents of the OS-level clipboard.
## Example
```rust
extern crate copypasta;
use copypasta::ClipboardContext;
fn example() {
let mut ctx = ClipboardContext::new().unwrap();
println!("{:?}", ctx.get_contents());
ctx.set_contents("some string".to_owned()).unwrap();
}
```
## API
The `ClipboardProvider` trait has the following functions:
```rust
fn get_contents(&mut self) -> Result<String, Box<Error>>;
fn set_contents(&mut self, String) -> Result<(), Box<Error>>;
```
`ClipboardContext` is a type alias for one of {`WindowsClipboardContext`, `OSXClipboardContext`, `X11ClipboardContext`, `NopClipboardContext`}, all of which implement `ClipboardProvider`. Which concrete type is chosen for `ClipboardContext` depends on the OS (via conditional compilation).
## License
`rust-clipboard` is dual-licensed under MIT and Apache2.
