Enum clang::Nullability

#[repr(C)]pub enum Nullability {
    NonNull,
    Nullable,
    Unspecified,
}

Indicates the nullability of a pointer type.

Variants

NonNull

Values of this type can never be null.

Nullable

Values of this type can be null.

Unspecified

Whether values of this type can be null is (explicitly) unspecified.
