Struct DiscardedOutputStream 

pub struct DiscardedOutputStream { /* private fields */ }

Marker stream for a stdio slot configured with std::process::Stdio::null().

The OS discards the child’s writes; no pipe is allocated and no reader task runs. The read_chunk_size and max_buffered_chunks accessors are present because OutputStream requires them, but they have no operational meaning for this variant and return zero.

Trait Implementations

impl Clone for DiscardedOutputStream

fn clone(&self) -> DiscardedOutputStream

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiscardedOutputStream

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl OutputStream for DiscardedOutputStream

fn read_chunk_size(&self) -> NumBytes

The maximum size of every chunk read by the backing stream_reader.

fn max_buffered_chunks(&self) -> usize

The number of chunks held by the underlying async channel.

fn name(&self) -> &'static str

Type of stream. Can be “stdout” or “stderr”. But we do not guarantee this output. It should only be used for logging/debugging.

impl PartialEq for DiscardedOutputStream

fn eq(&self, other: &DiscardedOutputStream) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
