Struct ThemeRegistry 

pub struct ThemeRegistry { /* private fields */ }

An ordered set of named themes (built-ins first, then custom), resolved by name. Cloned cheaply enough for the few entries a UI carries.

Implementations

impl ThemeRegistry

pub fn builtin() -> ThemeRegistry

A registry with only the built-in themes.

pub fn with_custom<I>(self, custom: I) -> ThemeRegistry

where I: IntoIterator<Item = (String, ThemeColors)>,

Adds custom themes, each replacing a built-in of the same name in place (keeping its position) or appended after the built-ins.

pub fn get(&self, name: &str) -> Option<ThemeColors>

The colors for name, if present.

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

The colors for name, falling back to the default theme when unknown.

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

Whether a theme with name exists.

pub fn names(&self) -> Vec<&str>

All theme names in order.

pub fn next(&self, current: &str) -> String

The name of the theme after current (wrapping). Unknown current starts from the first theme.
