Enum rustc_mir::transform::const_prop::ConstPropMode

pub(in transform::const_prop) enum ConstPropMode {
    FullConstProp,
    OnlyInsideOwnBlock,
    OnlyPropagateInto,
    NoPropagation,
}

The mode that ConstProp is allowed to run in for a given Local.

Variants

FullConstProp

The Local can be propagated into and reads of this Local can also be propagated.

OnlyInsideOwnBlock

The Local can only be propagated into and from its own block.

OnlyPropagateInto

The Local can be propagated into but reads cannot be propagated.

NoPropagation

The Local cannot be part of propagation at all. Any statement referencing it either for reading or writing will not get propagated.
