Implementations

impl ThemeSwitcher

pub fn new() -> ThemeSwitcher

Switcher over all built-in themes, starting at the first.

pub fn with_themes(themes: Vec<Theme>) -> ThemeSwitcher

Switcher over custom themes. An empty list falls back to the built-ins.

pub fn current(&self) -> &Theme

The active theme.

pub fn index(&self) -> usize

Index of the active theme.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Always false; a switcher holds at least one theme.

pub fn themes(&self) -> &[Theme]

All themes in order.

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

Names of all themes in order.

pub fn next(&mut self) -> &Theme

Advance (wrapping) and return the new active theme.

pub fn prev(&mut self) -> &Theme

Step back (wrapping) and return the new active theme.

pub fn set_index(&mut self, index: usize) -> &Theme

Jump to index, wrapping modulo the number of themes.

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

Select a theme by name (same normalisation as Theme::by_name). Returns false and keeps the selection when not found.
