Implementations

impl FastApiTheme

pub fn from_preset(preset: ThemePreset) -> Self

Create a theme from a preset.

pub fn fastapi() -> Self

Create the default FastAPI-inspired theme.

Colors chosen to match FastAPI documentation styling and Swagger UI conventions for familiarity.

pub fn neon() -> Self

Create a neon/cyberpunk theme with high contrast.

pub fn minimal() -> Self

Create a minimal grayscale theme with accent colors.

pub fn monokai() -> Self

Create a Monokai-inspired dark theme.

pub fn light() -> Self

Uses darker, more saturated colors that maintain good contrast against white or light-colored terminal backgrounds.

pub fn accessible() -> Self

Create a high-contrast accessible theme.

Designed to meet WCAG 2.1 Level AA contrast requirements (4.5:1 minimum). Uses bright, saturated colors for maximum visibility.

Color Choices

• All colors have >4.5:1 contrast ratio against dark backgrounds
• Uses pure, saturated terminal colors for maximum compatibility
• Semantic colors follow universal conventions (red=error, green=success)
• Avoids colors that may be difficult for colorblind users

let post_color = theme.http_method_color("post"); // case-insensitive

pub fn status_code_color(&self, code: u16) -> Color
