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

Returns self with the attr() set to [Attribute::Bold].

§Example

println!("{}", value.bold());

Returns self with the attr() set to [Attribute::Blink].

§Example

println!("{}", value.blink());

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();

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);
