The central functionality of a plugin. The trait bounds asure that each asynchronous task can receive a copy of the handler, so some state can be shared.

Associated Types

type Writer: AsyncWrite + Send + Unpin + 'static

The type where we write our responses to requests. Handling of incoming requests/notifications is done on the io loop, which passes the parsed messages to the handler.

Provided methods

fn handle_request<'life0, 'async_trait>(
    &'life0 self,
    _name: String,
    _args: Vec<Value>,
    _neovim: Neovim<Self::Writer>
) -> Pin<Box<dyn Future<Output = Result<Value, Value>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Handling an rpc request. The ID’s of requests are handled by the neovim instance.

fn handle_notify<'life0, 'async_trait>(
    &'life0 self,
    _name: String,
    _args: Vec<Value>,
    _neovim: Neovim<<Self as Handler>::Writer>
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Handling an rpc notification. Notifications are handled one at a time in the order in which they were received, and will block new requests from being received until handle_notify returns.
