Structs

MirPatch 🔒

This struct lets you “patch” a MIR body, i.e. modify it. You can queue up various changes, such as the addition of new statements and basic blocks and replacement of terminators, and then apply the queued changes all at once with apply. This is useful for MIR transformation passes.
