Enum FontStack 

pub enum FontStack {
    Stack(Vec<FontSelector>),
    Ref(FontRef),
}

Font stack that can be either a list of font selectors (resolved via fontconfig) or a direct FontRef (bypasses fontconfig entirely).

When a FontRef is used, it bypasses fontconfig resolution entirely and uses the pre-parsed font data directly. This is used for embedded fonts like Material Icons.

Variants

Stack(Vec<FontSelector>)

A stack of font selectors to be resolved via fontconfig First font is primary, rest are fallbacks

Ref(FontRef)

A direct reference to a pre-parsed font (e.g., embedded icon fonts) This font covers the entire Unicode range and has no fallbacks.

Implementations

impl FontStack

pub fn is_ref(&self) -> bool

Returns true if this is a direct FontRef

pub fn as_ref(&self) -> Option<&FontRef>

Returns the FontRef if this is a Ref variant

pub fn as_stack(&self) -> Option<&[FontSelector]>

Returns the font selectors if this is a Stack variant

pub fn first_selector(&self) -> Option<&FontSelector>

Returns the first FontSelector if this is a Stack variant, None if Ref

pub fn first_family(&self) -> &str

Returns the first font family name (for Stack) or a placeholder (for Ref)

Trait Implementations

impl Clone for FontStack

fn clone(&self) -> FontStack

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontStack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FontStack

fn default() -> Self

Returns the “default value” for a type.

impl Hash for FontStack

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FontStack

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
