Struct Trak 

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

The tracking (trak) table.

Fields

data: FontData<'a>

Implementations

impl<'a> Trak<'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 version(&self) -> MajorMinor

Version number of the tracking table (0x00010000 for the current version).

pub fn format(&self) -> u16

Format of the tracking table (set to 0).

pub fn horiz_offset(&self) -> Nullable<Offset16>

Offset from start of tracking table to TrackData for horizontal text (or 0 if none).

pub fn horiz(&self) -> Option<Result<TrackData<'a>, ReadError>>

Attempt to resolve horiz_offset.

pub fn vert_offset(&self) -> Nullable<Offset16>

Offset from start of tracking table to TrackData for vertical text (or 0 if none).

pub fn vert(&self) -> Option<Result<TrackData<'a>, ReadError>>

Attempt to resolve vert_offset.

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

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

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

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

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

Trait Implementations

impl<'a> Clone for Trak<'a>

fn clone(&self) -> Trak<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for Trak<'a>

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