Struct clap::builder::styling::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 + Clone

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>

Write the ANSI code

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

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>

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();

impl Style

Reflection

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

pub const fn get_bg_color(self) -> Option<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 effects are enabled

fn from(effects: Effects) -> Style

Converts to this type from the input type.

impl Hash for Style

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

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

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

This method tests for self and other values to be equal, and is used by ==.

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

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