Struct AsyncHandle

pub struct AsyncHandle { /* private fields */ }

Binding to libuv’s Async handle used to trigger the execution of a callback in the Neovim thread.

Implementations

impl AsyncHandle

pub fn new<E, Cb>(callback: Cb) -> Result<Self, Error>

where E: StdError + 'static, Cb: FnMut() -> Result<(), E> + 'static,

Registers a new callback on the Neovim event loop, returning an AsyncHandle which can be used to execute the callback from any thread. The callback will always be executed on the main thread.

pub fn send(&self) -> Result<(), Error>

Wakes up the Neovim event loop and executes the callback associated to this handle. It is safe to call this function from any thread. The callback will be called on the main thread.

NOTE: libuv will coalesce calls to AsyncHandle::send, that is, not every call to it will yield an execution of the callback. For example: if AsyncHandle::send is called 5 times in a row before the callback is called, the callback will only be called once. If AsyncHandle::send is called again after the callback was called, it will be called again.
