Enum AbiKind 

pub enum AbiKind {
    Ctx,
    Gc,
    RawI64,
    RawU32,
    Ptr,
}

The kind of one ABI parameter — what a value in that position is, which fixes the machine type the caller must pass.

Variants

Ctx

*mut RuntimeContext. Always the first parameter of every wrapper.

Gc

A GcRef — a non-null pointer to a GcHeader. Pointer-width.

RawI64

A raw, unboxed i64. Not a GC reference: never rooted, never traced.

RawU32

A raw, unboxed u32. Narrower than a machine word, so passing an i64 here is exactly the mismatch this manifest exists to prevent.

Ptr

A pointer-width raw word that is not a GcRef: a *const u8, a descriptor or schema pointer, a frame pointer, or a usize length.
