Struct WatchHandle 

pub struct WatchHandle { /* private fields */ }

A live watcher subscription. Dropping it stops receiving events.

Obtained from WorkspaceWatcher::watch. The adapter that implements WorkspaceWatcher maps platform-level file-system events into WorkspaceChange and publishes them to the application event bus.

Implementations

impl WatchHandle

pub fn new(receiver: Receiver<WorkspaceChange>) -> Self

Wrap a broadcast receiver. Used by WorkspaceWatcher implementations.

Public so an adapter crate can construct the handle it returns; the shape is otherwise opaque on purpose.

pub async fn recv(&mut self) -> Result<WorkspaceChange, RecvError>

Wait for the next change event.

pub fn try_recv(&mut self) -> Result<WorkspaceChange, TryRecvError>

Returns Some if a change is already waiting, None otherwise.

Trait Implementations

impl Debug for WatchHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
