Expand description

Outcome of a closure-compilation attempt. Kept ABI-compatible with the legacy crate::jit::cache_lookup_or_compile return tuple so the Vm::populate_jit_cache call site doesn’t have to re-shape its destructure.

Variants§

§

Compiled

The proto was lowered (or served from cache); the fields mirror the legacy 7-tuple returned by cache_lookup_or_compile.

Fields

§entry: *const u8

Mmap’d entry address; transmute to the matching unsafe extern "C" fn shape at the call site.

§num_args: u8

Argument count (0..=MAX_JIT_ARITY).

§returns_one: bool

True when the compiled chunk produces a single observable result (Op::Return1); false when it only side-effects.

§arg_float_mask: u8

Bit i set ↔ argument slot i is Value::Float.

§arg_table_mask: u8

Bit i set ↔ argument slot i is Value::Table.

§ret_is_float: bool

True when the chunk’s return value is float (only meaningful when returns_one is true).

§ret_is_table: bool

True when the chunk’s return value is Value::Table.

§

Skipped

The proto fell outside the whitelist or its compile pass bailed. The interpreter handles it unchanged.
