Struct ProcessStreamBuilder 

pub struct ProcessStreamBuilder;

Builder for selecting the output stream backend for one process stream.

Backend choice controls stream ownership and fanout. Delivery policy and replay policy are selected in later builder stages and are independent decisions. The Self::discard entry short-circuits the chain entirely for stdio that should be routed to /dev/null at the OS level.

Implementations

impl ProcessStreamBuilder

pub fn broadcast( self, ) -> PipedStreamConfig<BroadcastBackend, StreamConfigBuilder>

Selects the broadcast backend for this stream.

Use this when the same stdout or stderr stream must be consumed concurrently, such as logging plus readiness checks or logging plus collection.

pub fn single_subscriber( self, ) -> PipedStreamConfig<SingleSubscriberBackend, StreamConfigBuilder>

Selects the single-subscriber backend for this stream.

Use this when exactly one active consumer should own the stream and accidental concurrent fanout should be rejected early. This backend can reduce coordination overhead in some single-consumer paths, but delivery policy still determines lag behavior.

pub fn discard(self) -> DiscardedStreamConfig

Routes the matching child stdio slot to Stdio::null().

No pipe is allocated, no reader task is spawned, and the resulting stream is a DiscardedOutputStream that does not expose any consumer methods. Reach for this when only the exit status matters and the child’s output should be dropped at the OS level.

Trait Implementations

impl Clone for ProcessStreamBuilder

fn clone(&self) -> ProcessStreamBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessStreamBuilder

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

Formats the value using the given formatter.

impl PartialEq for ProcessStreamBuilder

fn eq(&self, other: &ProcessStreamBuilder) -> 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.
