Struct LocalFontIdentifier

pub struct LocalFontIdentifier {
    pub path: Atom,
    pub face_index: u16,
    pub named_instance_index: u16,
}

An identifier for a local font on systems using Freetype.

Fields

path: Atom

The path to the font.

face_index: u16

The variation index within the font.

named_instance_index: u16

The index of the named instance within the font.

For non-variable fonts, this is ignored.

Implementations

impl LocalFontIdentifier

pub fn index(&self) -> u32

pub fn named_instance_index(&self) -> u32

pub fn native_font_handle(&self) -> NativeFontHandle

pub fn font_data_and_index(&self) -> Option<FontDataAndIndex>

pub fn face_index_for_freetype(&self) -> u32

Fontconfig and FreeType use a packed format to represent face and named instance indexes in a single integer. The first 16 bits make up the named instance index and the second 16 bits make up the face index.

See https://freetype.org/freetype2/docs/reference/ft2-face_creation.html#ft_open_face for more information.

Trait Implementations

impl Clone for LocalFontIdentifier

fn clone(&self) -> LocalFontIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocalFontIdentifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LocalFontIdentifier

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for LocalFontIdentifier

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 MallocSizeOf for LocalFontIdentifier

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for LocalFontIdentifier

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

impl Serialize for LocalFontIdentifier

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
