Crate ffi_bridge 

ffi-bridge

Memory-safe Go↔Rust FFI boundary helpers.

This crate provides:

• FfiBuffer — heap-allocated byte buffer with explicit ownership semantics
• FfiString — UTF-8 string safe for crossing the FFI boundary
• FfiResult — C-ABI result type conveying either a payload or an error
• FfiError / FfiErrorCode — rich error taxonomy matching the C header
• Callback registry — register and invoke named callbacks across the FFI boundary
• catch_panic — converts Rust panics to FfiResult so they never cross the ABI

Safety contract

• All buffers and strings allocated by this crate must be freed by the corresponding ffi_*_free function exported from this crate.
• Panics are caught at every extern "C" boundary via catch_panic.
• No Rust type with a Drop impl is allowed to cross the FFI boundary as a value; only repr(C) POD structs may do so.
