Enum FontChainKeyOrRef 

pub enum FontChainKeyOrRef {
    Chain(FontChainKey),
    Ref(usize),
}

Either a FontChainKey (resolved via fontconfig) or a direct FontRef hash.

This enum cleanly separates:

• Chain: Fonts resolved through fontconfig with fallback support
• Ref: Direct FontRef that bypasses fontconfig entirely (e.g., embedded icon fonts)

Variants

Chain(FontChainKey)

Regular font chain resolved via fontconfig

Ref(usize)

Direct FontRef identified by pointer address (covers entire Unicode range, no fallbacks)

Implementations

impl FontChainKeyOrRef

pub fn from_font_stack(font_stack: &FontStack) -> Self

Create from a FontStack enum

pub fn is_ref(&self) -> bool

Returns true if this is a direct FontRef

pub fn as_ref_ptr(&self) -> Option<usize>

Returns the FontRef pointer if this is a Ref variant

pub fn as_chain(&self) -> Option<&FontChainKey>

Returns the FontChainKey if this is a Chain variant

Trait Implementations

impl Clone for FontChainKeyOrRef

fn clone(&self) -> FontChainKeyOrRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontChainKeyOrRef

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

Formats the value using the given formatter.

impl Hash for FontChainKeyOrRef

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 FontChainKeyOrRef

fn eq(&self, other: &FontChainKeyOrRef) -> 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.
