Crate oxideav_otf 

Pure-Rust OpenType / CFF font parser.

Scope:

• sfnt header + table directory walker (parser).
• CFF (Adobe TN5176) Top DICT / Name / String INDEX / Charset / Encoding / Private DICT / Local + Global Subrs, plus CID-keyed fonts (ROS + FDArray Font DICTs + FDSelect GID→FD routing, TN5176 §§18, 19).
• CFF2 (OpenType 1.9.1 §6–§8): header, Top DICT, GlobalSubrINDEX, CharStringINDEX, and FontDICTINDEX walks (the cff2 module defers variation-aware charstring decoding to a later round).
• Type 2 charstring interpreter (Adobe TN5177): every common path construction operator, the four flex variants, the deprecated four-operand seac endchar, hint-recording stubs (no enforcement; we anti-alias at >= 16 px), and subroutine resolution with the well-known 107 / 1131 / 32768 bias formula.
• Selected sfnt tables for metadata (head, hhea, maxp, hmtx, cmap formats 0/4/6/12, name, post, OS/2, GDEF, and the GSUB / GPOS headers with their ScriptList / FeatureList / LookupList walks).

The crate is read-only (parsing-only) and dependency-light: only oxideav-core for shared types. CFF2 charstring decoding (with blend / vsindex resolution against the VariationStore), per-glyph hinting interpretation, advanced GSUB/GPOS, and Bidi are deferred.

See README.md for a tour of the public API.
