Implementations

impl FontFeatures

pub fn disable_ligatures() -> Self

Disables calt.

pub fn tag_value_list(&self) -> &[(String, u32)]

Get the tag name list of the font OpenType features only enabled or disabled features are returned

pub fn is_calt_enabled(&self) -> Option<bool>

Returns whether the calt feature is enabled.

Returns None if the feature is not present.

Trait Implementations

impl Clone for FontFeatures

fn clone(&self) -> FontFeatures

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontFeatures

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

Formats the value using the given formatter.

impl Default for FontFeatures

fn default() -> FontFeatures

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FontFeatures

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FontFeatures

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 JsonSchema for FontFeatures

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn json_schema(_: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

impl PartialEq for FontFeatures

fn eq(&self, other: &FontFeatures) -> 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 FontFeatures

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&FontFeatures> for FontFeatures

type Error = Error

The type returned in the event of a conversion error.

fn try_from(features: &FontFeatures) -> Result<Self>

Performs the conversion.
