[][src]Struct yansi::Style

#[repr(packed)]
pub struct Style { /* fields omitted */ }

Represents a set of styling options.

See the crate level documentation for usage information.

Method Glossary

The Style structure exposes many methods for convenience. The majority of these methods are shared with Paint.

Foreground Color Constructors

Return a new Style structure with a foreground color applied.

Setters

Set a style property on a given Style structure.

These methods can be chained:

use yansi::{Style, Color::{Red, Magenta}};

Style::new(Red).bg(Magenta).underline().invert().italic().dimmed().bold();

Converters

Convert a Style into another structure.

Getters

Return information about a Style structure.

Raw Formatters

Write the raw ANSI codes for a given Style to any fmt::Write.

Methods

impl Style
[src]

Default style with the foreground set to color and no other set properties.

use yansi::Style;

let plain = Style::default();
assert_eq!(plain, Style::default());

Sets the foreground to color.

use yansi::{Color, Style};

let red_fg = Style::default().fg(Color::Red);

Sets the background to color.

use yansi::{Color, Style};

let red_bg = Style::default().bg(Color::Red);

Sets self to be masked.

An item with masked styling is not written out when painting is disabled during Display or Debug invocations. When painting is enabled, masking has no effect.

use yansi::Style;

let masked = Style::default().mask();

// "Whoops! " will only print when coloring is enabled.
println!("{}Something happened.", masked.paint("Whoops! "));

Sets self to be wrapping.

A wrapping Style converts all color resets written out by the internal value to the styling of itself. This allows for seamless color wrapping of other colored text.

Performance

In order to wrap an internal value, the internal value must first be written out to a local buffer and examined. As a result, displaying a wrapped value is likely to result in a heap allocation and copy.

use yansi::{Paint, Style, Color};

let inner = format!("{} and {}", Paint::red("Stop"), Paint::green("Go"));
let wrapping = Style::new(Color::Blue).wrap();

// 'Hey!' will be unstyled, "Stop" will be red, "and" will be blue, and
// "Go" will be green. Without a wrapping `Paint`, "and" would be
// unstyled.
println!("Hey! {}", wrapping.paint(inner));

Enables the bold style on self .

use yansi::Paint; 

println!("Using bold: {}", Paint::new("hi").bold());

Enables the dimmed style on self .

use yansi::Paint; 

println!("Using dimmed: {}", Paint::new("hi").dimmed());

Enables the italic style on self .

use yansi::Paint; 

println!("Using italic: {}", Paint::new("hi").italic());

Enables the underline style on self .

use yansi::Paint; 

println!("Using underline: {}", Paint::new("hi").underline());

Enables the blink style on self .

use yansi::Paint; 

println!("Using blink: {}", Paint::new("hi").blink());

Enables the invert style on self .

use yansi::Paint; 

println!("Using invert: {}", Paint::new("hi").invert());

Enables the hidden style on self .

use yansi::Paint; 

println!("Using hidden: {}", Paint::new("hi").hidden());

Enables the strikethrough style on self .

use yansi::Paint; 

println!("Using strikethrough: {}", Paint::new("hi").strikethrough());

Constructs a new Paint structure that encapsulates item with the style set to self.

use yansi::{Style, Color};

let alert = Style::new(Color::Red).bold().underline();
println!("Alert: {}", alert.paint("This thing happened!"));

Returns the foreground color of self.

use yansi::{Style, Color};

let plain = Style::default();
assert_eq!(plain.fg_color(), Color::Unset);

let red = plain.fg(Color::Red);
assert_eq!(red.fg_color(), Color::Red);

Returns the foreground color of self.

use yansi::{Style, Color};

let plain = Style::default();
assert_eq!(plain.bg_color(), Color::Unset);

let white = plain.bg(Color::White);
assert_eq!(white.bg_color(), Color::White);

Returns true if self is masked.

use yansi::Style;

let plain = Style::default();
assert!(!plain.is_masked());

let masked = plain.mask();
assert!(masked.is_masked());

Returns true if self is wrapping.

use yansi::Style;

let plain = Style::default();
assert!(!plain.is_wrapping());

let wrapping = plain.wrap();
assert!(wrapping.is_wrapping());

Returns true if the bold property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_bold());

let styled = plain.bold(); 
assert!(styled.is_bold());

Returns true if the dimmed property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_dimmed());

let styled = plain.dimmed(); 
assert!(styled.is_dimmed());

Returns true if the italic property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_italic());

let styled = plain.italic(); 
assert!(styled.is_italic());

Returns true if the underline property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_underline());

let styled = plain.underline(); 
assert!(styled.is_underline());

Returns true if the blink property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_blink());

let styled = plain.blink(); 
assert!(styled.is_blink());

Returns true if the invert property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_invert());

let styled = plain.invert(); 
assert!(styled.is_invert());

Returns true if the hidden property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_hidden());

let styled = plain.hidden(); 
assert!(styled.is_hidden());

Returns true if the strikethrough property is set on self .

use yansi::Style; 

let plain = Style::default();
assert!(!plain.is_strikethrough());

let styled = plain.strikethrough(); 
assert!(styled.is_strikethrough());

Writes the ANSI code prefix for the currently set styles.

This method is intended to be used inside of fmt::Display and fmt::Debug implementations for custom or specialized use-cases. Most users should use Paint for all painting needs.

This method writes the ANSI code prefix irrespective of whether painting is currently enabled or disabled. To write the prefix only if painting is enabled, condition a call to this method on Paint::is_enabled().

Example

use std::fmt;
use yansi::Style;

struct CustomItem {
    item: u32,
    style: Style
}

impl fmt::Display for CustomItem {
    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
        self.style.fmt_prefix(f)?;
        write!(f, "number: {}", self.item)?;
        self.style.fmt_suffix(f)
    }
}

Writes the ANSI code suffix for the currently set styles.

This method writes the ANSI code suffix irrespective of whether painting is currently enabled or disabled. To write the suffix only if painting is enabled, condition a call to this method on Paint::is_enabled().

impl fmt::Display for CustomItem {
    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
        self.style.fmt_prefix(f)?;
        write!(f, "number: {}", self.item)?;
        self.style.fmt_suffix(f)
    }
}
