Enum rustc_const_eval::interpret::Place

pub enum Place<Prov: Provenance = AllocId> {
    Ptr(MemPlace<Prov>),
    Local {
        frame: usize,
        local: Local,
    },
}

Variants

Ptr(MemPlace<Prov>)

A place referring to a value allocated in the Memory system.

Local

Fields

frame: usize

local: Local

To support alloc-free locals, we are able to write directly to a local. (Without that optimization, we’d just always be a MemPlace.)

Implementations

impl<Prov: Provenance> Place<Prov>

pub fn assert_local(&self) -> (usize, Local)

Asserts that this points to some local variable. Returns the frame idx and the variable idx.

Trait Implementations

impl<Prov: Clone + Provenance> Clone for Place<Prov>

fn clone(&self) -> Place<Prov>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Prov: Debug + Provenance> Debug for Place<Prov>

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

Formats the value using the given formatter.

impl<Prov: Copy + Provenance> Copy for Place<Prov>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
