pub struct Error;
mtls
only.Expand description
The error type which is returned from formatting a message into a stream.
This type does not support transmission of an error other than that an error occurred. Any extra information must be arranged to be transmitted through some other means.
An important thing to remember is that the type fmt::Error
should not be
confused with std::io::Error
or std::error::Error
, which you may also
have in scope.
Examples
use std::fmt::{self, write};
let mut output = String::new();
if let Err(fmt::Error) = write(&mut output, format_args!("Hello {}!", "world")) {
panic!("An error occurred");
}

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

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

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

.
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>

set to

.
Example
println!("{}", value.underline());
source§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
Returns self

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);
