Struct Style

pub struct Style { /* private fields */ }

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

impl Style

Core

pub const fn new() -> Style

No effects enabled

Examples

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

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()));

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()));

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()));

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

Set text effects

Examples

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

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

Render the ANSI code

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

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

Available on crate feature std only.

Write the ANSI code

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.

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.

impl Style

Convenience

pub const fn bold(self) -> Style

Apply bold effect

Examples

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

pub const fn dimmed(self) -> Style

Apply dimmed effect

Examples

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

pub const fn italic(self) -> Style

Apply italic effect

Examples

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

pub const fn underline(self) -> Style

Apply underline effect

Examples

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

pub const fn blink(self) -> Style

Apply blink effect

Examples

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

pub const fn invert(self) -> Style

Apply invert effect

Examples

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

pub const fn hidden(self) -> Style

Apply hidden effect

Examples

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

pub const fn strikethrough(self) -> Style

Apply strikethrough effect

Examples

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

Reflection

pub const fn get_fg_color(self) -> Option<Color>

Get the foreground color

pub const fn get_bg_color(self) -> Option<Color>

Get the background color

pub const fn get_underline_color(self) -> Option<Color>

pub const fn get_effects(self) -> Effects

pub const fn is_plain(self) -> bool

Check if no styling is enabled

impl Default for Style

fn default() -> Style

Returns the “default value” for a type.

impl Display for Style

let style: anstyle::Style = anstyle::Effects::BOLD.into();

fn from(effects: Effects) -> Style

Converts to this type from the input type.

impl Hash for Style

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Style

fn cmp(&self, other: &Style) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq<Effects> for Style

let effects = anstyle::Effects::BOLD;
assert_eq!(anstyle::Style::new().effects(effects), effects);
assert_ne!(anstyle::Effects::UNDERLINE | effects, effects);

fn eq(&self, other: &Effects) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for Style

fn eq(&self, other: &Style) -> bool

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
