Struct ANSISyntaxTheme 

pub struct ANSISyntaxTheme {
    pub background: Option<Color>,
    pub foreground: Option<Color>,
    pub styles: HashMap<String, Style>,
}

A syntax theme that maps to ANSI colors (lightweight, no Pygments dependency).

Provides a simple token-to-style mapping for common syntax token types like “keyword”, “string”, “comment”, “number”, “type”, and “function”. Pre-built themes are available via ANSISyntaxTheme::monokai and ANSISyntaxTheme::default_light.

Fields

background: Option<Color>

Optional background color for the code block.

foreground: Option<Color>

Optional default foreground color.

styles: HashMap<String, Style>

Token name to style mapping.

Implementations

impl ANSISyntaxTheme

pub fn new() -> Self

Create a new empty ANSISyntaxTheme.

pub fn set(&mut self, token: &str, style: Style)

Set the style for a token type.

Common token names include: "comment", "keyword", "string", "number", "type", "function".

pub fn get(&self, token: &str) -> Option<&Style>

Get the style for a token type, if one has been set.

pub fn monokai() -> Self
