Struct Style 

pub struct Style(/* private fields */);

A combinatorial style such as bold, italics, dimmed, etc.

Creation

Style::default() returns a Style with no style switches activated and is the default method of creating a plain Style.

Style from a set of Styless / Styles iterator

Style implements FromIter<Styles> which means that it is possible to do the following:

let style = Style::from_iter([Styles::Bold, Styles::Italic, Styles::Strikethrough]);
for styles in [Styles::Bold, Styles::Italic, Styles::Strikethrough] {
    assert!(style.contains(styles));
}

As you can see, this is a good thing to keep in mind, although for most cases, where you’re not setting styles dynamically and are simply creating a pre-defined set of styles, using Default and then using the builder-style methods is likely prettier.

let many_styles = Style::default()
    .bold()
    .underline()
    .italic()
    .blink();

Implementation of logical bitwise operators

Style implements bitwise logical operations that operate on the held style switches collectively. By far the most common and useful is the bitwise ‘or’ operator | which combines two styles, merging their combined styles into one. Example:

let only_bold = Style::from(Styles::Bold);
// This line is actually an example of `Styles`'s bitwise logic impls but still.
let underline_and_italic = Styles::Underline | Styles::Italic;
let all_three = only_bold | underline_and_italic;

assert!(all_three.contains(Styles::Bold)
    && all_three.contains(Styles::Underline)
    && all_three.contains(Styles::Italic));

This functionality also allows for easily turning off styles of one Styles using another by combining the & and ! operators.

let mut very_loud_style = Style::default()
    .bold()
    .underline()
    .italic()
    .strikethrough()
    .hidden();

// Oops! Some of those should not be in there!
// This Style now has all styles _except_ the two we don't want
// (hidden and strikethough).
let remove_mask =
    !Style::from_iter([Styles::Hidden, Styles::Strikethrough]);
very_loud_style &= remove_mask;

// `very_loud_style` no longer contains the undesired style
// switches...
assert!(!very_loud_style.contains(Styles::Hidden)
    && !very_loud_style.contains(Styles::Strikethrough));
// ...but it retains everything else!
assert!(very_loud_style.contains(Styles::Bold));

Implementations

impl Style

pub fn contains(self, style: Styles) -> bool

Check if the current style has one of Styles switched on.

let colored = "".bold().italic();
assert_eq!(colored.style.contains(Styles::Bold), true);
assert_eq!(colored.style.contains(Styles::Italic), true);
assert_eq!(colored.style.contains(Styles::Dimmed), false);

pub fn add(&mut self, two: Styles)

Adds the two style switch to this Style.

let cstr = "".red().bold();
let mut style = cstr.style;
style.add(Styles::Italic);
let mut cstr2 = "".blue();
cstr2.style = style;

assert!(cstr2.style.contains(Styles::Bold));
assert!(cstr2.style.contains(Styles::Italic));
assert_eq!(cstr2.fgcolor, Some(Color::Blue));

pub fn remove(&mut self, two: Styles)

Turns off a style switch.

use colored::*;
let cstr = "".red().bold().italic();
let mut style = cstr.style;
style.remove(Styles::Italic);
let mut cstr2 = "".blue();
cstr2.style = style;
assert!(cstr2.style.contains(Styles::Bold));
assert!(!cstr2.style.contains(Styles::Italic));
assert_eq!(cstr2.fgcolor, Some(Color::Blue));

pub fn bold(self) -> Self

Makes this Style include Bold.
