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.

Unstyled Constructors

Return a new Style structure with no styling applied.

• Style::new()
• Style::masked()

Foreground Color Constructors

Return a new Style structure with a foreground color applied.

• Style::black()
• Style::red()
• Style::green()
• Style::yellow()
• Style::blue()
• Style::purple()
• Style::cyan()
• Style::white()

Getters

Return information about a Style structure.

• style.fg_color()
• style.bg_color()
• style.is_masked()
• style.is_bold()
• style.is_dimmed()
• style.is_italic()
• style.is_underline()
• style.is_blink()
• style.is_invert()
• style.is_hidden()
• style.is_strikethrough()

Setters

Set a style property on a given Style structure.

• style.fg(color: Color)
• style.bg(color: Color)
• style.mask()
• style.bold()
• style.dimmed()
• style.italic()
• style.underline()
• style.blink()
• style.invert()
• style.hidden()
• style.strikethrough()

These methods can be chained:

use yansi::Style;

Style::red().underline().invert().italic().dimmed().bold();

Converters

Convert a Style into another structure.

• style.paint<T>(item: T) -> Paint<T>

Raw Formatters

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

• style.fmt_prefix(f: &mut fmt::Formatter)
• style.fmt_suffix(f: &mut fmt::Formatter)

Methods

impl Style

pub fn new() -> Style

Default, unstylized Style. This is identical to Style::default().

use yansi::Style;

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

pub fn masked() -> Style

Default, unstylized but masked Style. Aside from masking, this is identical to Style::default().

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

pub fn red() -> Style

Constructs a new Stylestructure with the foreground color set to red.

use yansi::Style; 

let red = Style::red();
println!("This is going to be red: {}", red.paint("yay!"));

pub fn green() -> Style

Constructs a new Stylestructure with the foreground color set to green.

use yansi::{Style, Color};

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

pub fn fmt_prefix(&self, f: &mut Formatter) -> Result

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)
    }
}

pub fn fmt_suffix(&self, f: &mut Formatter) -> Result

Writes the ANSI code suffix 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 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().

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)
    }
}
