Enum rustc_const_eval::interpret::place::Place

source · [−]

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

Variants

`Ptr(MemPlace<Tag>)`

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

source

impl<Tag: Provenance> Place<Tag>

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.
