Struct Base 

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

The BASE (Baseline) table

Fields

data: FontData<'a>

Implementations

impl<'a> Base<'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

(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.

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

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

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

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

Trait Implementations

Performs copy-assignment from source.

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

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