Implementations

impl<'a> CmapSubtable<'a>

pub fn map_glyph(&self, ch: u32) -> Result<Option<u16>, ParseError>

pub fn to_owned(&self) -> Option<OwnedCmapSubtable>

Returns an owned::CmapSubtable. Will only return None if self is CmapSubtable::Format2 as support for converting from this format is not yet implemented.

pub fn mappings_fn(
&self,
callback: impl FnMut(u32, u16)
) -> Result<(), ParseError>

Extract all the mappings from the sub-table.

Trait Implementations

type HostType = CmapSubtable<'a>

fn read(ctxt: &mut ReadCtxt<'a>) -> Result<Self, ParseError>

impl<'a> WriteBinary<&CmapSubtable<'a>> for CmapSubtable<'a>

type Output = ()

The type of the value returned by write.

fn write<C: WriteContext>(
ctxt: &mut C,
table: &CmapSubtable<'a>
) -> Result<(), WriteError>

Write the binary representation of Self to ctxt.
