Enum rustc::mir::repr::Lvalue

pub enum Lvalue<'tcx> {
    Var(u32),
    Temp(u32),
    Arg(u32),
    Static(DefId),
    ReturnPointer,
    Projection(Box<LvalueProjection<'tcx>>),
}

Unstable (rustc_private)

A path to a value; something that can be evaluated without changing or disturbing program state.

Variants

Var(u32)

Unstable (rustc_private)

local variable declared by the user

Temp(u32)

Unstable (rustc_private)

temporary introduced during lowering into MIR

Arg(u32)

Unstable (rustc_private)

formal parameter of the function; note that these are NOT the bindings that the user declares, which are vars

Static(DefId)

Unstable (rustc_private)

static or static mut variable

ReturnPointer

Unstable (rustc_private)

the return pointer of the fn

Projection(Box<LvalueProjection<'tcx>>)

Unstable (rustc_private)

projection out of an lvalue (access a field, deref a pointer, etc)
