Type Alias Base

pub type Base<'a> = TableRef<'a, BaseMarker>;

The BASE (Baseline) table

Aliased Type

struct Base<'a> { /* private fields */ }

Implementations

impl<'a> Base<'a>

pub fn version(&self) -> MajorMinor

(major, minor) Version for the BASE table (1,0) or (1,1)

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

Offset to horizontal Axis table, from beginning of BASE table (may be NULL)

pub fn horiz_axis(&self) -> Option<Result<Axis<'a>, ReadError>>

Attempt to resolve horiz_axis_offset.

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

Offset to vertical Axis table, from beginning of BASE table (may be NULL)

pub fn vert_axis(&self) -> Option<Result<Axis<'a>, ReadError>>

Attempt to resolve vert_axis_offset.

pub fn item_var_store_offset(&self) -> Option<Nullable<Offset32>>

Offset to Item Variation Store table, from beginning of BASE table (may be null)

pub fn item_var_store( &self, ) -> Option<Result<ItemVariationStore<'a>, ReadError>>

Attempt to resolve item_var_store_offset.

impl<'a, T> TableRef<'a, T>

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) -> &T

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.

Trait Implementations

impl<'a> FontRead<'a> for Base<'a>

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

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

impl TopLevelTable for Base<'_>

const TAG: Tag

BASE

impl<'a, T: Clone> Clone for TableRef<'a, T>

fn clone(&self) -> TableRef<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.
