Struct StyleSpec 

pub struct StyleSpec {
    pub inherit: Option<ElementName>,
    pub fg: Option<ColorRef>,
    pub bg: Option<ColorRef>,
    pub modifiers: ModifierSet,
    pub scale: Option<f32>,
    pub family: Option<FamilyId>,
    pub weight: Option<Weight>,
}

How an element is styled, by reference. The form a mode default, a theme override, or a buffer-local remap is written in. Resolution (crate::registry) produces a concrete Style.

Fields

inherit: Option<ElementName>

Inherit another element’s resolved style; this spec’s set fields override. Resolved by walking the chain at build time.

fg: Option<ColorRef>

bg: Option<ColorRef>

modifiers: ModifierSet

scale: Option<f32>

Relative height ratio (emacs :height float). Resolution quantizes to fixed-point FontScale.

family: Option<FamilyId>

weight: Option<Weight>

Implementations

impl StyleSpec

pub fn new() -> Self

An empty spec — resolves to Style::empty() (or the inherit base) with no overrides.

pub fn inherit(self, name: impl Into<ElementName>) -> Self

Inherit another element’s resolved style.

pub fn fg(self, fg: impl Into<ColorRef>) -> Self

Set the foreground by reference (palette key, literal, or default). Accepts a PaletteKey, a Color, or a ColorRef.

pub fn bg(self, bg: impl Into<ColorRef>) -> Self

Set the background by reference.

pub fn bold(self) -> Self

pub fn italic(self) -> Self

pub fn underline(self) -> Self

pub fn dim(self) -> Self

pub fn reverse(self) -> Self

pub fn no_bold(self) -> Self

Explicitly clear a modifier the inherit base set.

pub fn scale(self, ratio: f32) -> Self

Set the relative height ratio (rich vocabulary).

pub fn family(self, family: FamilyId) -> Self

pub fn weight(self, weight: Weight) -> Self
