Enum CtfeValidationMode

Source 
pub enum CtfeValidationMode {
    Static {
        mutbl: Mutability,
    },
    Promoted,
    Const {
        allow_immutable_unsafe_cell: bool,
    },
}
Expand description

Extra things to check for during validation of CTFE results.

Variants§

§

Static

Validation of a static

Fields

§mutbl: Mutability
§

Promoted

Validation of a promoted.

§

Const

Validation of a const. allow_immutable_unsafe_cell says whether we allow UnsafeCell in immutable memory (which is the case for the top-level allocation of a const, where this is fine because the allocation will be copied at each use site).

Fields

§allow_immutable_unsafe_cell: bool
