GlyphAssembly: OpenType MATH glyph assembly passed to the engine as an opaque pointer, freed by free_ot_assembly.
PortableClock
PortableError: The error that ended the last run and where the input stood when it did.
PortableFontMetrics
PortableFormatImage: A sealed engine state, decoded and validated once when loaded, that every engine instance clones.
PortableGlyphBounds: A glyph’s advance and control box in points, y up, as XeTeX’s getGlyphWidth and getGlyphBounds give them.
PortableHostBox
PortableHostBoxGlyph
PortableHostBoxRequest
PortableHostBoxRule
PortableHostBoxRun
PortableLinebreakRequest
PortableMathAssemblyPart: One part of an OpenType MATH glyph assembly in scaled points, as hb_ot_math_glyph_part_t.
PortableMathVariant: A larger OpenType MATH glyph variant, its advance in scaled points and -1 when there is none.
PortableNativeGlyph
PortableNativeGlyphMetrics
PortableNativeTextMetrics
PortableNodeHandle: An engine node handle, only the engine hands these out.
PortableNodeSnapshot: A read only copy of one node’s fields, dimensions in scaled points.
PortableResourceRequestRecord
PortableSourceSpan
PortableTexEngine
ResourceRequest

FormatImageError: Why a serialized format image was rejected.
InputEncoding: XeTeX input decoding mode from xetex.h, auto is resolved at open time and ICU mappings read as bytes.
PortableErrorKind: What ended a run with an error.
PortableHostBoxStyle
PortableMathKernCorner: A corner of an OpenType MathKernInfo record (mirrors hb_ot_math_kern_t).
PortableNoadKind: The atom type of a math noad.
PortableNodeKind: What a node in engine memory is.
ResourceKind

FILE_SIZE_PROBE_MODE: Request mode of a \filesize probe, which reads a resource only to measure it and may find nothing.
SANDBOX_OP_BUDGET: Default sandbox budget of commands and expansions, PortableTexEngine::set_sandbox_op_budget changes it.
