Module runtime 

Runtime prelude for auto-patched Web2C/C2Rust engine source. Generated code must be lowered from raw globals into PortableTexState before it is linked into mathtex-engine.

EngineProfile

GlyphAssembly

Heap-owned OpenType MATH glyph assembly handed to the engine as an opaque pointer by get_ot_assembly_ptr and reclaimed by free_ot_assembly.

PortableClock

PortableFontMetrics

PortableFormatImage

PortableLinebreakRequest

PortableMathAssemblyPart

One part of an OpenType MATH glyph assembly, all measurements in scaled points (mirrors hb_ot_math_glyph_part_t / ttf-parser GlyphPart).

PortableMathVariant

A larger OpenType MATH glyph variant: the variant glyph id and its advance in scaled points (-1 advance means “no such variant”).

InputEncoding

Input decoding mode for a [PortableFileHandle], mirroring XeTeX’s encoding modes (xetex.h): Bytes corresponds to RAW. AUTO/ICUMAPPING are not stored here — AUTO is resolved to a concrete mode at open time (BOM sniff), and ICU mappings degrade to Bytes.

PortableMathKernCorner

A corner of an OpenType MathKernInfo record (mirrors hb_ot_math_kern_t).

Functions

memory_word_bytes

Size in bytes of one TeX memory_word in this build. Real XeTeX packs it to 8; this engine uses a 16-byte word (the four_quarters view is u16, but two_halves/cint keep the c2rust 32-bit alignment).
