Struct FileChannel

pub struct FileChannel { /* private fields */ }

FileChannel is a handle for one end of a bidirectional channel.

Implementations

impl FileChannel

pub const fn new( read_handle: FileDescriptor, write_handle: FileDescriptor, ) -> Self

Create a new FileChannel from two file descriptors.

pub const fn read_handle(&self) -> FileDescriptor

Returns the a copy of the FileDescriptor used for the read end of the channel.

pub const fn write_handle(&self) -> FileDescriptor

Returns the a copy of the FileDescriptor used for the write end of the channel.

Trait Implementations

impl Channel for FileChannel

fn read<'life0, 'life1, 'async_trait>( &'life0 self, buf: &'life1 mut [u8], ) -> Pin<Box<dyn Future<Output = ChannelResult<usize>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Asynchronously read data from the channel into the provided buffer.

fn read_exact<'life0, 'life1, 'async_trait>( &'life0 self, buf: &'life1 mut [u8], ) -> Pin<Box<dyn Future<Output = ChannelResult<usize>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Asynchronously read exactly buf.len() bytes into buf from the channel.

fn write<'life0, 'life1, 'async_trait>( &'life0 self, buf: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = ChannelResult<usize>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Asynchronously write the provided buffer to the channel.
