Enum OutputEvent 

#[non_exhaustive]
pub enum OutputEvent {
    Stdout(OutputLine),
    Stderr(OutputLine),
}

An event produced by a child process: a decoded line from stdout or stderr.

Yielded by RunningProcess::output_events, which merges both streams into a single, ordered sequence.

Non-exhaustive: a future release may add a third kind of event (e.g. a lifecycle marker) without a breaking change, so a match on OutputEvent needs a _ arm. Each per-stream line is an OutputLine (rather than a bare String) so per-line metadata can be attached there without a breaking change either.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Stdout(OutputLine)

A line from the child’s standard output.

Stderr(OutputLine)

A line from the child’s standard error.

Implementations

impl OutputEvent

pub fn text(&self) -> Option<&str>

The decoded text of this event’s line, if it carries one. Some for Stdout/Stderr; None for a future non-line event kind. Convenience for consumers that don’t care which stream a line came from.

Trait Implementations

impl Clone for OutputEvent

fn clone(&self) -> OutputEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutputEvent

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

Formats the value using the given formatter.

impl Eq for OutputEvent

impl PartialEq for OutputEvent

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