Struct CharacterVariantParams 

pub struct CharacterVariantParams<'a> {
    data: FontData<'a>,
}

featureParams for ‘cv01’-‘cv99’

Fields

data: FontData<'a>

Implementations

impl<'a> CharacterVariantParams<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a>>( &self, offset: O, ) -> Result<R, ReadError>

Resolve the provided offset from the start of this table.

pub fn offset_data(&self) -> FontData<'a>

Return a reference to this table’s raw data.

We use this in the compile crate to resolve offsets.

pub fn shape(&self) -> &Self

👎Deprecated: just use the base type directly

Return a reference to the table’s ‘Shape’ struct.

This is a low level implementation detail, but it can be useful in some cases where you want to know things about a table’s layout, such as the byte offsets of specific fields.

pub fn format(&self) -> u16

Format number is set to 0.

pub fn feat_ui_label_name_id(&self) -> NameId

The ‘name’ table name ID that specifies a string (or strings, for multiple languages) for a user-interface label for this feature. (May be NULL.)

pub fn feat_ui_tooltip_text_name_id(&self) -> NameId

The ‘name’ table name ID that specifies a string (or strings, for multiple languages) that an application can use for tooltip text for this feature. (May be NULL.)

pub fn sample_text_name_id(&self) -> NameId

The ‘name’ table name ID that specifies sample text that illustrates the effect of this feature. (May be NULL.)

pub fn num_named_parameters(&self) -> u16

Number of named parameters. (May be zero.)

pub fn first_param_ui_label_name_id(&self) -> NameId

The first ‘name’ table name ID used to specify strings for user-interface labels for the feature parameters. (Must be zero if numParameters is zero.)

pub fn char_count(&self) -> u16

The count of characters for which this feature provides glyph variants. (May be zero.)

pub fn character(&self) -> &'a [BigEndian<Uint24>]

The Unicode Scalar Value of the characters for which this feature provides glyph variants.

pub fn format_byte_range(&self) -> Range<usize>

pub fn feat_ui_label_name_id_byte_range(&self) -> Range<usize>

pub fn feat_ui_tooltip_text_name_id_byte_range(&self) -> Range<usize>

pub fn sample_text_name_id_byte_range(&self) -> Range<usize>

pub fn num_named_parameters_byte_range(&self) -> Range<usize>

pub fn first_param_ui_label_name_id_byte_range(&self) -> Range<usize>

pub fn char_count_byte_range(&self) -> Range<usize>

pub fn character_byte_range(&self) -> Range<usize>

Trait Implementations

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for CharacterVariantParams<'a>

fn read(data: FontData<'a>) -> Result<Self, ReadError>

Read an instance of Self from the provided data, performing validation.

impl Format<u16> for CharacterVariantParams<'_>

const FORMAT: u16 = 0

The format value for this table.

impl<'a> MinByteRange<'a> for CharacterVariantParams<'a>

fn min_byte_range(&self) -> Range<usize>
