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: 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 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>
