Struct DtactChildStdout 

pub struct DtactChildStdout(/* private fields */);

One end of a child process’s stdout pipe.

Exclusively owned by whoever holds it (returned by take_stdout on DtactChild) — each async op temporarily moves the handle into a pool closure and gets it back in the result, never shared behind a lock.

Implementations

impl DtactChildStdout

pub async fn read(&mut self, buf: Vec<u8>) -> Result<(usize, Vec<u8>)>

Read from the child’s stdout on the process pool into buf, returning the number of bytes read and the buffer back.

Errors

Returns whatever the underlying blocking Read::read on the pipe returns.

Panics

Panics if called again while a previous call on the same &mut self hasn’t finished — see DtactChildStdin::write’s doc for why this is unreachable through safe code.
