Trait Implementations

impl HostInputStream for FsInputStreamWrapper

fn read(&mut self, size: usize) -> StreamResult<Bytes>

Reads up to size bytes, returning a buffer holding these bytes on success.

fn skip(&mut self, nelem: usize) -> StreamResult<usize>

Same as the read method except that bytes are skipped.

fn blocking_read<'life0, 'async_trait>( &'life0 mut self, size: usize, ) -> Pin<Box<dyn Future<Output = Result<Bytes, StreamError>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Send + 'async_trait,

Similar to read, except that it blocks until at least one byte can be read.

fn blocking_skip<'life0, 'async_trait>( &'life0 mut self, nelem: usize, ) -> Pin<Box<dyn Future<Output = Result<usize, StreamError>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Send + 'async_trait,

Similar to skip, except that it blocks until at least one byte can be skipped.

fn cancel<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Send + 'async_trait,

Cancel any asynchronous work and wait for it to wrap up.

impl Subscribe for FsInputStreamWrapper

fn ready<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

An asynchronous function which resolves when this object’s readiness operation is ready.
