Source§fn get_string<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Option<String>>
fn get_string<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Option<String>>
Get a string from the backing store. Returns None if there is no value for the given key.
Source§fn get_int<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Option<i64>>
fn get_int<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Option<i64>>
Get an int from the backing store. Returns None if there is no value for the given key.
Source§fn get_bool<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Option<bool>>
fn get_bool<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Option<bool>>
Get a boolean from the backing store. Returns None if there is no value for the given key.

fn set_string<'a>( &'a mut self, key: &'a str, value: &'a str, ) -> BoxFuture<'a, Result<(), Self::Error>>
Set a value to be stored in the backing store. The implementation should cache the value until the |commit()| fn is called, and then persist all cached values at that time.

&'a mut self,
key: &'a str,
value: i64,
) -> BoxFuture<'a, Result<(), Self::Error>>
fn set_int<'a>( &'a mut self, key: &'a str, value: i64, ) -> BoxFuture<'a, Result<(), Self::Error>>
Set a value to be stored in the backing store. The implementation should cache the value until the |commit()| fn is called, and then persist all cached values at that time.

fn set_bool<'a>( &'a mut self, key: &'a str, value: bool, ) -> BoxFuture<'a, Result<(), Self::Error>>
Set a value to be stored in the backing store. The implementation should cache the value until the |commit()| fn is called, and then persist all cached values at that time.
Source§fn commit(&mut self) -> BoxFuture<'_, Result<(), Self::Error>>
fn commit(&mut self) -> BoxFuture<'_, Result<(), Self::Error>>
Persist all cached values to storage.

§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>
renamed to 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);
