    data: TableDataRef<'a, MathKernInfoFixedHeader>,
}

MathKernInfo

Fields

data: TableDataRef<'a, MathKernInfoFixedHeader>

Implementations

impl<'a> MathKernInfo<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a, Args = ()>>( &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 math_kern_coverage_offset(&self) -> Offset16

Offset to the Coverage table, from the beginning of the MathKernInfo table.

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

Attempt to resolve math_kern_coverage_offset.

pub fn math_kern_count(&self) -> u16

Number of MathKernInfoRecords. Should coincide with the number of covered glyphs.

pub fn math_kern_info_records(&self) -> &'a [MathKernInfoRecord]

Array of MathKernInfoRecords, one for each covered glyph.

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

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

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

impl<'a> MathKernInfo<'a>

pub fn kern( &self, glyph: GlyphId, corner: MathKernCorner, ) -> Option<MathKern<'a>>

The kerning for one corner of a glyph, or None where the table does not cover the glyph or gives that corner nothing.

Trait Implementations
