Struct StdoutCapture

pub struct StdoutCapture { /* private fields */ }

StdoutCapture holds the standard output from multiple processes.

The most common pattern of usage is to capture together the output from a starting process and all sub-processes. E.g. Hide output of sub-processes during testing.

Implementations

impl StdoutCapture

pub fn new(echo: bool) -> Self

pub fn only_reference(&self) -> bool

Returns true if this is the only reference to the outputs.

pub fn next(&self) -> Self

Returns a clone of StdoutCapture pointing to the next stream

pub fn is_empty(&self) -> bool

Returns true if all streams are empty

pub fn content(&self) -> String

Returns stream’s content

pub fn push_str(&self, content: &str)

Add string to end of the stream

Trait Implementations

impl Clone for StdoutCapture

fn clone(&self) -> StdoutCapture

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StdoutCapture

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

Formats the value using the given formatter.

impl Display for StdoutCapture

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

Formats the value using the given formatter.

impl PartialEq for StdoutCapture

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

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

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

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