Struct CidCMap 

pub struct CidCMap { /* private fields */ }

A parsed CID CMap that maps character codes to CIDs.

Used by predefined CMaps (e.g., Adobe-Japan1) and embedded CID CMaps that use begincidchar/endcidchar and begincidrange/endcidrange sections. Unlike CMap which maps to Unicode strings, this maps character codes to numeric CID values.

Implementations

impl CidCMap

pub fn parse(data: &[u8]) -> Result<Self, BackendError>

Parse a CID CMap from its raw byte content.

Extracts begincidchar/endcidchar and begincidrange/endcidrange sections to build the character code → CID mapping table.

pub fn lookup(&self, code: u32) -> Option<u32>

Look up the CID for a character code.

pub fn len(&self) -> usize

Returns the number of mappings in this CID CMap.

pub fn is_empty(&self) -> bool

Returns true if this CID CMap has no mappings.

pub fn name(&self) -> Option<&str>

CMap name.

pub fn writing_mode(&self) -> u8

Writing mode: 0 = horizontal, 1 = vertical.
