    data: TableDataRef<'a, MathTopAccentAttachmentFixedHeader>,
}

MathTopAccentAttachment

Fields

data: TableDataRef<'a, MathTopAccentAttachmentFixedHeader>

Implementations

impl<'a> MathTopAccentAttachment<'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 top_accent_coverage_offset(&self) -> Offset16

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

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

Attempt to resolve top_accent_coverage_offset.

pub fn top_accent_attachment_count(&self) -> u16

Number of top accent attachment point values. Should coincide with the number of covered glyphs.

pub fn top_accent_attachment(&self) -> &'a [MathValueRecord]

Array of MathValueRecords defining top accent attachment points for each covered glyph.

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

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

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

impl MathTopAccentAttachment<'_>

pub fn attachment(&self, glyph: GlyphId) -> Option<i32>

The horizontal position at which an accent sits above a glyph, in design units, or None where the table does not cover it.

pub fn attachment_for_ppem( &self, glyph: GlyphId, ppem: u16, ) -> Option<MathValue>

The horizontal position at which an accent sits above a glyph, as read at a size, or None where the table does not cover it.

fn record(&self, glyph: GlyphId) -> Option<&MathValueRecord>

Trait Implementations
