Struct StderrStream 

pub struct StderrStream { /* private fields */ }

Cloneable handle to the kernel’s stderr output stream.

Multiple pipeline stages can write concurrently. The receiver side is drained by the kernel after each statement (or by a background task).

Uses UnboundedSender which is Clone + Send + Sync — safe across tokio::spawn boundaries without Arc<Mutex<..>>.

Implementations

impl StderrStream

pub fn write(&self, data: &[u8])

Write raw bytes to the stderr stream.

Non-blocking. If the receiver has been dropped, the data is silently discarded (same as writing to a closed pipe).

pub fn write_str(&self, msg: &str)

Write a UTF-8 string to the stderr stream.

Convenience for builtins that produce string stderr.
