pub const fn complement(self) -> Namespace

The bitwise negation (!) of the bits in self, truncating the result.

impl Namespace

pub const fn iter(&self) -> Iter<Namespace>

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);

where S: Into<Style>,

Apply a style wholesale to self. Any previous style is replaced. Read more
