async_pipe

Struct PipeReader

Source 
pub struct PipeReader { /* private fields */ }
Expand description

The read half of the pipe which implements AsyncRead.

Implementations§

Source§

impl PipeReader

Source

pub fn close(&self) -> Result<()>

Closes the pipe, any further read will return EOF and any further write will raise an error.

Source

pub fn is_flushed(&self) -> Result<bool>

It returns true if the next data chunk is written by the writer and consumed by the reader; Otherwise it returns false.
