Enum CompletionTag 

#[repr(u32)]
pub enum CompletionTag {
    Normal = 0,
    Throw = 1,
    Suspend = 2,
    FatalTrap = 3,
}

The completion class returned by a native entry, as the raw u32 result.

Variants

Normal = 0

out.value is the return value.

Throw = 1

out.value is a rooted error handle.

Suspend = 2

A resume offset was written to the frame; out.value is the yield.

FatalTrap = 3

out.value encodes a TrapRecordId; control leaves to the runtime.
