Enum UnwindOrigin 

pub enum UnwindOrigin {
    Site(u32),
    Call(u32),
}

Why a cleanup block is reachable.

Cleanup blocks run while a panic unwinds. They are only reachable if the panic that triggers them can actually happen, so suppressing that panic must also suppress everything reachable only through its cleanup path.

Variants

Site(u32)

Reached by the unwind edge of a panic raised in this body. The index selects a member of Body::sites.

Call(u32)

Reached by the unwind edge of a call in this body, and therefore live only if that callee can itself unwind. The index selects a member of Body::calls.
