Struct CffHeader 

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

Compact Font Format table header

Fields

data: FontData<'a>

Implementations

impl<'a> CffHeader<'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 major(&self) -> u8

Format major version (starting at 1).

pub fn minor(&self) -> u8

Format minor version (starting at 0).

pub fn hdr_size(&self) -> u8

Header size (bytes).

pub fn off_size(&self) -> u8

Absolute offset size.

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

Padding bytes before the start of the Name INDEX.

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

Remaining table data.

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

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

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

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

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

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

Trait Implementations

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for CffHeader<'a>

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

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

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