§impl<T> Slice<T>
impl<T> Slice<T>
pub fn get_index(&self, index: usize) -> Option<&T>
pub fn get_index(&self, index: usize) -> Option<&T>
Get a value by index.
Valid indices are 0 <= index < self.len().
pub fn get_range<R>(&self, range: R) -> Option<&Slice<T>>where
R: RangeBounds<usize>,
pub fn get_range<R>(&self, range: R) -> Option<&Slice<T>>where
R: RangeBounds<usize>,
Returns a slice of values in the given range of indices.
Valid indices are 0 <= index < self.len().
pub fn split_at(&self, index: usize) -> (&Slice<T>, &Slice<T>)
pub fn split_at(&self, index: usize) -> (&Slice<T>, &Slice<T>)
Divides one slice into two at an index.
Panics if index > len.
pub fn split_first(&self) -> Option<(&T, &Slice<T>)>
pub fn split_first(&self) -> Option<(&T, &Slice<T>)>
Returns the first value and the rest of the slice,
or None if it is empty.
pub fn split_last(&self) -> Option<(&T, &Slice<T>)>
pub fn split_last(&self) -> Option<(&T, &Slice<T>)>
Returns the last value and the rest of the slice,
or None if it is empty.
pub fn binary_search(&self, x: &T) -> Result<usize, usize>where
T: Ord,
pub fn binary_search(&self, x: &T) -> Result<usize, usize>where
T: Ord,
Search over a sorted set for a value.
Returns the position where that value is present, or the position where it can be inserted
to maintain the sort. See slice::binary_search for more details.
Computes in O(log(n)) time, which is notably less scalable than looking the value up in
the set this is a slice from using IndexSet::get_index_of, but this can also position
missing values.
pub fn binary_search_by<'a, F>(&'a self, f: F) -> Result<usize, usize>
pub fn binary_search_by<'a, F>(&'a self, f: F) -> Result<usize, usize>
Search over a sorted set with a comparator function.
Returns the position where that value is present, or the position where it can be inserted
to maintain the sort. See slice::binary_search_by for more details.
Computes in O(log(n)) time.
pub fn binary_search_by_key<'a, B, F>(
&'a self,
b: &B,
f: F,
) -> Result<usize, usize>
pub fn binary_search_by_key<'a, B, F>( &'a self, b: &B, f: F, ) -> Result<usize, usize>
Search over a sorted set with an extraction function.
Returns the position where that value is present, or the position where it can be inserted
to maintain the sort. See slice::binary_search_by_key for more details.
Computes in O(log(n)) time.
pub fn partition_point<P>(&self, pred: P) -> usize
pub fn partition_point<P>(&self, pred: P) -> usize
Returns the index of the partition point of a sorted set according to the given predicate (the index of the first element of the second partition).
See slice::partition_point for more details.
Computes in O(log(n)) time.

§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};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
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():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§fn attr(&self, value: Attribute) -> Painted<&T>
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().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);§impl<T> Pipe for Twhere

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
