Struct TableDirectory 

pub struct TableDirectory<'a> { /* private fields */ }

The OpenType Table Directory

Implementations

impl<'a> TableDirectory<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O, R>(&self, offset: O) -> Result<R, ReadError>

where O: Offset, R: FontRead<'a>,

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) -> &TableDirectory<'a>

👎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 sfnt_version(&self) -> u32

0x00010000 or 0x4F54544F

pub fn num_tables(&self) -> u16

Number of tables.

pub fn search_range(&self) -> u16

pub fn entry_selector(&self) -> u16

pub fn range_shift(&self) -> u16

pub fn table_records(&self) -> &'a [TableRecord]

Table records array—one for each top-level table in the font

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

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

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

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

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

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

Trait Implementations

impl<'a> Clone for TableDirectory<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for TableDirectory<'_>

fn default() -> TableDirectory<'_>

Returns the “default value” for a type.

impl<'a> FontRead<'a> for TableDirectory<'a>

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

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

impl<'a> MinByteRange<'a> for TableDirectory<'a>

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

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