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 mask(&self) -> Painted<&T>

Returns self with the quirk() set to [Quirk::Mask].

§Example
println!("{}", value.mask());
§

fn wrap(&self) -> Painted<&T>

Returns self with the quirk() set to [Quirk::Wrap].

§Example
println!("{}", value.wrap());
§

fn linger(&self) -> Painted<&T>

Returns self with the quirk() set to [Quirk::Linger].

§Example
println!("{}", value.linger());
§

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.

Returns self with the quirk() set to [Quirk::Clear].

§Example
println!("{}", value.clear());
§

fn resetting(&self) -> Painted<&T>

Returns self with the quirk() set to [Quirk::Resetting].

§Example
println!("{}", value.resetting());
§

fn bright(&self) -> Painted<&T>

Returns self with the quirk() set to [Quirk::Bright].

§Example
println!("{}", value.bright());
§

fn on_bright(&self) -> Painted<&T>

Returns self with the quirk() set to [Quirk::OnBright].

§Example
println!("{}", value.on_bright());
§

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);
