Struct rustc_mir_build::build::expr::as_place::PlaceBuilder

pub(in build::expr::as_place) struct PlaceBuilder<'tcx> {
    local: Local,
    projection: Vec<PlaceElem<'tcx>>,
}

PlaceBuilder is used to create places during MIR construction. It allows you to "build up" a place by pushing more and more projections onto the end, and then convert the final set into a place using the into_place method.

This is used internally when building a place for an expression like a.b.c. The fields b and c can be progressively pushed onto the place builder that is created when converting a.

Fields

local: Local

projection: Vec<PlaceElem<'tcx>>
