Stream for the select() function.
Implementations§
Source§impl<St1, St2> Select<St1, St2>
impl<St1, St2> Select<St1, St2>
Sourcepub fn get_ref(&self) -> (&St1, &St2)
pub fn get_ref(&self) -> (&St1, &St2)
Acquires a reference to the underlying streams that this combinator is pulling from.
Sourcepub fn get_mut(&mut self) -> (&mut St1, &mut St2)
pub fn get_mut(&mut self) -> (&mut St1, &mut St2)
Acquires a mutable reference to the underlying streams that this combinator is pulling from.
Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this combinator.
Sourcepub fn get_pin_mut(
self: Pin<&mut Select<St1, St2>>,
) -> (Pin<&mut St1>, Pin<&mut St2>)
pub fn get_pin_mut( self: Pin<&mut Select<St1, St2>>, ) -> (Pin<&mut St1>, Pin<&mut St2>)
Acquires a pinned mutable reference to the underlying streams that this combinator is pulling from.
Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this combinator.
Sourcepub fn into_inner(self) -> (St1, St2)
pub fn into_inner(self) -> (St1, St2)
Consumes this combinator, returning the underlying streams.
Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};

This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():

fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

Enables the yansi Quirk value.

wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().

fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.

fn try_flatten_unordered( self, limit: impl Into<Option<usize>>, ) -> TryFlattenUnordered<Self>
Flattens a stream of streams into just one continuous stream. Produced streams
will be polled concurrently and any errors will be passed through without looking at them.
If the underlying base stream returns an error, it will be immediately propagated. Read more
