Struct HmtxExtended 

pub struct HmtxExtended<'a> {
    data: TableDataRef<'a, HmtxExtendedFixedHeader>,
    number_of_h_metrics: u32,
}

HMTX horizontal metrics (ISO/IEC 14496-22:2026, 5.1.11).

Fields

data: TableDataRef<'a, HmtxExtendedFixedHeader>

number_of_h_metrics: u32

Implementations

impl<'a> HmtxExtended<'a>

pub fn read( data: FontData<'a>, number_of_h_metrics: u32, ) -> Result<Self, ReadError>

A constructor that requires additional arguments.

This type requires some external state in order to be parsed.

impl<'a> HmtxExtended<'a>

pub const MIN_SIZE: usize = 0

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 h_metrics(&self) -> &'a [LongMetric]

pub fn left_side_bearings(&self) -> &'a [BigEndian<i16>]

pub(crate) fn number_of_h_metrics(&self) -> u32

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

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

impl HmtxExtended<'_>

pub fn advance(&self, glyph_id: GlyphId) -> Option<u16>

Returns the advance width for the given glyph identifier.

pub fn side_bearing(&self, glyph_id: GlyphId) -> Option<i16>

Returns the left side bearing for the given glyph identifier.

Trait Implementations

impl<'a> Clone for HmtxExtended<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for HmtxExtended<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> FontRead<'a> for HmtxExtended<'a>

fn read_with_args(data: FontData<'a>, args: u32) -> Result<Self, ReadError>

Read an item, performing validation.

impl<'a> From<HmtxExtended<'a>> for GlyphMetricRecords<'a>

fn from(table: HmtxExtended<'a>) -> Self

Converts to this type from the input type.

impl<'a> MinByteRange<'a> for HmtxExtended<'a>

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

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

impl ReadArgs for HmtxExtended<'_>

type Args = u32
