source§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();source§fn bright_black(&self) -> Painted<&T>

source§fn bright_magenta(&self) -> Painted<&T>

source§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();source§fn on_primary(&self) -> Painted<&T>

fn on_bright_blue(&self) -> Painted<&T>
Returns self with the
bg()
set to

Example

fn on_bright_magenta(&self) -> Painted<&T>
Returns self with the
bg()
set to
Color::BrightMagenta.
Example
println!("{}", value.on_bright_magenta());source§fn on_bright_cyan(&self) -> Painted<&T>
fn on_bright_cyan(&self) -> Painted<&T>
Returns self with the
bg()
set to
Color::BrightCyan.
Example
println!("{}", value.on_bright_cyan());source§fn on_bright_white(&self) -> Painted<&T>
fn on_bright_white(&self) -> Painted<&T>
Returns self with the
bg()
set to
Color::BrightWhite.
Example
println!("{}", value.on_bright_white());source§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();source§fn underline(&self) -> Painted<&T>
fn underline(&self) -> Painted<&T>
Returns self with the
attr()
set to
Attribute::Underline.
Example
println!("{}", value.underline());source§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
Returns self with the
attr()
set to
Attribute::RapidBlink.
Example
println!("{}", value.rapid_blink());source§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();source§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);
