Expand description

Filesystem watch port with debounced event delivery.

Required Methods§

Source

fn watch<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path, debounce_ms: u64, ) -> Pin<Box<dyn Future<Output = Result<WatchHandle>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Begin watching path (non-recursive) with debounce_ms coalescing.

Source

fn recv_event<'life0, 'life1, 'async_trait>( &'life0 self, handle: &'life1 WatchHandle, timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<Option<WatchEvent>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Receive the next debounced event, waiting up to timeout.

Source

fn unwatch<'life0, 'life1, 'async_trait>( &'life0 self, handle: &'life1 WatchHandle, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Stop watching and release resources for handle.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
