Enum rustc_target::abi::PointerKind

pub enum PointerKind {
    Shared,
    Frozen,
    UniqueBorrowed,
    UniqueOwned,
}

Variants

Shared

Most general case, we know no restrictions to tell LLVM.

Frozen

&T where T contains no UnsafeCell, is noalias and readonly.

UniqueBorrowed

&mut T which is noalias but not readonly.

UniqueOwned

Box<T>, unlike UniqueBorrowed, it also has noalias on returns.

Trait Implementations

impl Clone for PointerKind

fn clone(&self) -> PointerKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PointerKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
