Struct FeatureName

#[repr(C, packed(1))]
pub struct FeatureName {
    pub feature: BigEndian<u16>,

}

Type, flags and names for a feature.

Fields

feature: BigEndian<u16>

Feature type.

n_settings: BigEndian<u16>

The number of records in the setting name array.

setting_table_offset: BigEndian<Offset32>

Offset in bytes from the beginning of this table to this feature’s setting name array. The actual type of record this offset refers to will depend on the exclusivity value, as described below.

feature_flags: BigEndian<u16>

Flags associated with the feature type.

name_index: BigEndian<NameId>

The name table index for the feature’s name.

Implementations

impl FeatureName

pub fn feature(&self) -> u16

Feature type.

pub fn n_settings(&self) -> u16

The number of records in the setting name array.

pub fn setting_table_offset(&self) -> Offset32

Offset in bytes from the beginning of this table to this feature’s setting name array. The actual type of record this offset refers to will depend on the exclusivity value, as described below.

pub fn setting_table<'a>( &self, data: FontData<'a>, ) -> Result<SettingNameArray<'a>, ReadError>

Offset in bytes from the beginning of this table to this feature’s setting name array. The actual type of record this offset refers to will depend on the exclusivity value, as described below.

The data argument should be retrieved from the parent table By calling its offset_data method.

pub fn feature_flags(&self) -> u16

Flags associated with the feature type.

pub fn name_index(&self) -> NameId

The name table index for the feature’s name.

impl FeatureName

pub fn is_exclusive(&self) -> bool

Returns true if the feature settings are mutually exclusive.

pub fn default_setting_index(&self) -> u16

Returns the index of the default setting for the feature.

fn clone(&self) -> FeatureName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureName

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

Formats the value using the given formatter.

impl FixedSize for FeatureName

const RAW_BYTE_LEN: usize = 12usize
