Struct StderrReceiver 

pub struct StderrReceiver { /* private fields */ }

Receiving end of the stderr stream.

Owned by the kernel. Call drain_lossy() to collect all pending bytes as a UTF-8 string (with lossy decode at this boundary).

Implementations

impl StderrReceiver

pub fn drain_lossy(&mut self) -> String

Drain all pending bytes and decode as UTF-8 (lossy).

This is the single presentation boundary where bytes become a String. Multi-byte characters that were split across chunks are reassembled here because all chunks are concatenated before decoding.

Returns an empty string if no messages are pending. Non-blocking — returns immediately with whatever is available.
