Struct Theme 

pub struct Theme { /* private fields */ }

Resolved highlight-group → style map. Theme is materialized state: every group has its final Style baked in. Construct via smelt_tui::theme::compile or hand-build with Theme::set.

Implementations

impl Theme

pub fn new() -> Theme

pub fn set(&mut self, name: impl Into<String>, style: Style)

Set name to style. Overwrites any prior value.

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

Resolve a name to its current Style. Unknown names return Style::default().

pub fn resolve(&self, hl: HlGroup) -> Style

Resolve a HlGroup to its current Style. Anonymous style ids fall through to the global anon registry; everything else returns Style::default().

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

Get-or-mint the HlGroup id for name.

pub fn contains(&self, hl: HlGroup) -> bool

True iff this Theme has a Style registered for hl. False means resolve will fall back to the anon registry or Style::default().

pub fn is_light(&self) -> bool

pub fn set_light(&mut self, light: bool)

pub fn iter(&self) -> impl Iterator<Item = (HlGroup, &Style)>

Iterator over (HlGroup, &Style) for every group set on this theme. Order is unspecified.

pub fn len(&self) -> usize

Number of groups set on this theme.

pub fn is_empty(&self) -> bool
