mojo-rs-c-api

Export of the compatible public Mojo C System ABI (epoch 1).

Status: Scaffolded (structure only; no behavior yet).

Requirements (Phase 6)

• Exact symbol names, calling conventions, integer widths, struct sizes, alignments, enum/flag values.
• Correct option-structure version behavior (old sizes accepted).
• Correct null-pointer handling.
• No panic may cross the ABI boundary — all panics contained and converted to safe failure behavior.
• Ownership transitions exactly match the C contract.
• ABI courts compare exported symbol sets, header compilation, constants, struct sizes, field offsets, alignments, and unchanged C/C++ clients.

Structure

• types.rs — mirror of the pinned C types (ground truth: atlas/reference).
• symbols.rs — #[no_mangle] extern "C" exports.
• containment.rs — panic containment (catch_unwind at the boundary).
• versioning.rs — option-struct version handling.
