Struct IconProviderInner

pub struct IconProviderInner {
    pub icons: BTreeMap<String, BTreeMap<String, RefAny>>,
    pub resolver: IconResolverCallbackType,
}

Expand description

Inner data for IconProviderHandle - all fields behind single mutex

Fields§

§icons: BTreeMap<String, BTreeMap<String, RefAny>>

Nested map: pack_name → (icon_name → RefAny) Differentiation between Image/Font/SVG is via RefAny::downcast

§resolver: IconResolverCallbackType

The resolver callback

Implementations§

impl IconProviderInner

pub fn lookup_spec(&self, spec: &str) -> Option<RefAny>

Resolves an icon SPEC to registered icon data.

A spec is a comma-separated fallback list of entries, each either a bare icon name ("content_copy", searched across all packs in registration order, first match wins) or a pack-qualified name ("material-icons:save", searched only in that pack). The first entry that resolves wins, so markup can express per-platform fallbacks: <icon>ios:open_menu,kde:three-lines,menu</icon>. Icon names are case-insensitive; pack names are case-sensitive.
