Struct rustc::mir::Projection

pub struct Projection<'tcx, B, V> {
    pub base: B,
    pub elem: ProjectionElem<'tcx, V>,
}

🔬 This is a nightly-only experimental API. (rustc_private)

The Projection data structure defines things of the form B.x or *B or B[index]. Note that it is parameterized because it is shared between Constant and Lvalue. See the aliases LvalueProjection etc below.
