Struct Style

Source
pub struct Style { /* private fields */ }
Expand description

ANSI Text styling

You can print a Style to render the corresponding ANSI code. Using the alternate flag # will render the ANSI reset code, if needed. Together, this makes it convenient to render styles using inline format arguments.

§Examples

let style = anstyle::Style::new().bold();

let value = 42;
println!("{style}{value}{style:#}");

Implementations§

Source§

impl Style

§Core

Source

pub const fn new() -> Style

No effects enabled

§Examples
let style = anstyle::Style::new();
Source

pub const fn fg_color(self, fg: Option<Color>) -> Style

Set foreground color

§Examples
let style = anstyle::Style::new().fg_color(Some(anstyle::AnsiColor::Red.into()));
Source

pub const fn bg_color(self, bg: Option<Color>) -> Style

Set background color

§Examples
let style = anstyle::Style::new().bg_color(Some(anstyle::AnsiColor::Red.into()));
Source

pub const fn underline_color(self, underline: Option<Color>) -> Style

Set underline color

§Examples
let style = anstyle::Style::new().underline_color(Some(anstyle::AnsiColor::Red.into()));
Source

pub const fn effects(self, effects: Effects) -> Style

Set text effects

§Examples
let style = anstyle::Style::new().effects(anstyle::Effects::BOLD | anstyle::Effects::UNDERLINE);
Source

pub fn render(self) -> impl Display + Copy

Render the ANSI code

Style also implements Display directly, so calling this method is optional.

Source

pub fn write_to(self, write: &mut dyn Write) -> Result<(), Error>

Available on crate feature std only.

Write the ANSI code

Source

pub fn render_reset(self) -> impl Display + Copy

Renders the relevant Reset code

Unlike Reset::render, this will elide the code if there is nothing to reset.

Source

pub fn write_reset_to(self, write: &mut dyn Write) -> Result<(), Error>

Available on crate feature std only.

Write the relevant Reset code

Unlike Reset::render, this will elide the code if there is nothing to reset.
