Enum metered_wasmi::isa::Keep

pub enum Keep {
    None,
    Single,
}

Should we keep a value before "discarding" a stack frame?

Note that this is a enum since Wasm doesn't support multiple return values at the moment.

Variants

NoneSingle

Pop one value from the yet-to-be-discarded stack frame to the current stack frame.
