Struct ComputedStyle 

pub struct ComputedStyle {

    pub dark: String,
    pub mid: String,
    pub symbol: String,
    pub head: String,
    pub grey: String,
    pub bright: String,
    pub margin_spaces: String,
    pub blockquote: String,
    pub codebg: String,
    pub link: String,
    pub codepad: (String, String),
    pub list_indent: String,
    pub dark_fg: String,
    pub dark_bg: String,
    pub mid_fg: String,
    pub symbol_fg: String,
    pub head_fg: String,
    pub grey_fg: String,
    pub bright_fg: String,
}

Pre-computed ANSI color strings.

These values are computed from StyleConfig by applying HSV multipliers to the base color. Each string is formatted for ANSI escape sequences, e.g., “48;23;15m” for background colors or “255;128;64m” for foreground.

Fields

dark: String

Dark color (for backgrounds, code block bg). Format: “r;g;bm”

mid: String

Mid color (for secondary elements). Format: “r;g;bm”

symbol: String

Symbol color (for special characters, bullets). Format: “r;g;bm”

head: String

Head color (for headers). Format: “r;g;bm”

grey: String

Grey color (for muted text, blockquote bars). Format: “r;g;bm”

bright: String

Bright color (for emphasis, links). Format: “r;g;bm”

margin_spaces: String

Margin spaces string (e.g., “ “ for margin=2).

blockquote: String

Block quote prefix string with ANSI styling.

codebg: String

Code block background ANSI sequence.

link: String

Link color ANSI sequence.

codepad: (String, String)

Code block padding characters (left, right). Used for pretty padding around code blocks.

list_indent: String

List indent string.

dark_fg: String

Full ANSI foreground escape for dark.

dark_bg: String

Full ANSI background escape for dark.

mid_fg: String

Full ANSI foreground escape for mid.

symbol_fg: String

Full ANSI foreground escape for symbol.

head_fg: String

Full ANSI foreground escape for head.

grey_fg: String

Full ANSI foreground escape for grey.

bright_fg: String

Full ANSI foreground escape for bright.

Implementations

impl ComputedStyle

pub fn from_config(config: &StyleConfig) -> Self

Compute style values from a StyleConfig.

This applies the HSV multipliers to the base color to generate all derived colors, then formats them as ANSI escape sequences.

Arguments

• config - The style configuration to compute from

Example

use streamdown_config::{StyleConfig, ComputedStyle};

let config = StyleConfig::default();
let computed = ComputedStyle::from_config(&config);

// Use the computed dark background
let bg_escape = format!("\x1b[48;2;{}", computed.dark);

pub fn fg(&self, name: &str) -> &str

Get the foreground ANSI escape for a specific style.

pub fn bg(&self, name: &str) -> &str

Get the background ANSI escape for a specific style.

pub fn style_fg(&self, name: &str, text: &str) -> String

Format text with a specific foreground style.

pub fn heading(&self, level: u8, text: &str) -> String

Create a heading line with the head color.

pub fn code_start(&self, language: Option<&str>, width: usize) -> String

Create a code block start line.

pub fn quote(&self, text: &str, depth: usize) -> String

Create a blockquote line.

pub fn bullet(&self, indent: usize) -> String

Create a list bullet.

pub fn list_number(&self, indent: usize, num: usize) -> String

Create an ordered list number.

Trait Implementations

impl Clone for ComputedStyle

fn clone(&self) -> ComputedStyle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ComputedStyle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ComputedStyle

fn default() -> ComputedStyle

Returns the “default value” for a type.
