Struct ExtensionPosFormat1 

pub struct ExtensionPosFormat1<'a, T = ()> {
    data: FontData<'a>,
    offset_type: PhantomData<*const T>,
}

Extension Positioning Subtable Format 1

Fields

data: FontData<'a>

offset_type: PhantomData<*const T>

Implementations

impl<'a> ExtensionPosFormat1<'a, ()>

pub(crate) fn into_concrete<T>(self) -> ExtensionPosFormat1<'a, T>

impl<'a, T> ExtensionPosFormat1<'a, T>

pub(crate) fn of_unit_type(&self) -> ExtensionPosFormat1<'a, ()>

Replace the specific generic type on this implementation with ()

impl<'a, T> ExtensionPosFormat1<'a, T>

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 pos_format(&self) -> u16

Format identifier: format = 1

pub fn extension_lookup_type(&self) -> u16

Lookup type of subtable referenced by extensionOffset (i.e. the extension subtable).

pub fn extension_offset(&self) -> Offset32

Offset to the extension subtable, of lookup type extensionLookupType, relative to the start of the ExtensionPosFormat1 subtable.

pub fn extension(&self) -> Result<T, ReadError>

where T: FontRead<'a>,

Attempt to resolve extension_offset.

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

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

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

Trait Implementations

impl<'a, T: Clone> Clone for ExtensionPosFormat1<'a, T>

fn clone(&self) -> ExtensionPosFormat1<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T> FontRead<'a> for ExtensionPosFormat1<'a, T>

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

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

impl Format<u16> for ExtensionPosFormat1<'_>

const FORMAT: u16 = 1

The format value for this table.

impl<'a, T> MinByteRange<'a> for ExtensionPosFormat1<'a, T>

fn min_byte_range(&self) -> Range<usize>

fn min_table_bytes(&self) -> &'a [u8]
