Struct OsPipeReader 

pub struct OsPipeReader { /* private fields */ }

Owned OS kernel pipe reader half behind a single use slot. Clone shares the slot; take transfers the handle exactly once so no parent copy survives spawn to starve the consumer of EOF. Backed by std::io::pipe (stable since Rust 1.87): pipe on Unix, CreatePipe on Windows.

Implementations

impl OsPipeReader

pub fn take(&self) -> Result<PipeReader>

Take the handle for Stdio::from. Bails deterministically if the descriptor was already consumed so a second spawn can never reuse a spent pipe or leave stdio unbound.

Trait Implementations

impl Clone for OsPipeReader

fn clone(&self) -> OsPipeReader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
