AllocFlags

rustc_middle::mir::interpret::allocation

Struct AllocFlags 

Source 
struct AllocFlags {
    align: Align,
    mutability: Mutability,
    all_zero: bool,
}
Expand description

Helper struct that packs an alignment, mutability, and “all bytes are zero” flag together.

Alignment values always have 2 free high bits, and we check for this in our Encodable impl.
