Struct SinglePosFormat2 

pub struct SinglePosFormat2<'a> { /* private fields */ }

Single Adjustment Positioning Format 2: Array of Positioning Values

Implementations

impl<'a> SinglePosFormat2<'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 pos_format(&self) -> u16

Format identifier: format = 2

pub fn coverage_offset(&self) -> Offset16

Offset to Coverage table, from beginning of SinglePos subtable.

pub fn coverage(&self) -> Result<CoverageTable<'a>, ReadError>

Attempt to resolve coverage_offset.

pub fn value_format(&self) -> ValueFormat

Defines the types of data in the ValueRecords.

pub fn value_count(&self) -> u16

Number of ValueRecords — must equal glyphCount in the Coverage table.

pub fn value_records(&self) -> ComputedArray<'a, ValueRecord>

Array of ValueRecords — positioning values applied to glyphs.

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

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

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

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

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

Trait Implementations
