Enum Stream 

pub enum Stream {
    StandardError,
    StandardOutput,
}

The stream of a command that produced a line of output

A command writes its result to one stream and its diagnostics to another, and a reader of the output has to know which of the two it reads. A line carries this value, so that a caller can show a diagnostic apart from a result, or drop one of the two.

A command has these two output streams and no other, so a match on the value needs no arm for a stream that a later release adds.

Examples

use kawauso_process::run::Stream;

assert_eq!(Stream::StandardError.to_string(), "standard error");

Variants

StandardError

The stream on which a command states why it stopped

StandardOutput

The stream on which a command writes its result

Trait Implementations

impl Clone for Stream

fn clone(&self) -> Stream

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Stream

impl Debug for Stream

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

Formats the value using the given formatter.

impl Display for Stream

Names the stream for a reader

The name is the one that the documentation of an operating system uses, so that a log line names the stream that a reader looks for.

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

Formats the value using the given formatter.

impl Eq for Stream

impl Hash for Stream

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Stream

fn cmp(&self, other: &Stream) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Stream

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Stream

fn partial_cmp(&self, other: &Stream) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
