Expand description

Pipe-specific operations

This trait extends StreamIpcOps with pipe-specific functionality.

Required Methods§

Source

fn has_readers(&self) -> bool

Check if there are readers on the other end

Source

fn has_writers(&self) -> bool

Check if there are writers on the other end

Source

fn buffer_size(&self) -> usize

Get the buffer size of the pipe

Source

fn available_bytes(&self) -> usize

Get the number of bytes currently in the pipe buffer

Source

fn is_readable(&self) -> bool

Check if this end of the pipe is readable

Source

fn is_writable(&self) -> bool

Check if this end of the pipe is writable

Provided Methods§

Source

fn as_selectable(&self) -> Option<&dyn Selectable>

Optional capability: expose select/pselect readiness/wait interface.

By default, pipes are not exposed via this hook unless the implementation also implements Selectable and overrides this to return Some(self).
