Struct rustc::ty::MethodCall

pub struct MethodCall {
    pub expr_id: NodeId,
    pub autoderef: u32,
}

Unstable (rustc_private)

With method calls, we store some extra information in side tables (i.e method_map). We use MethodCall as a key to index into these tables instead of just directly using the expression's NodeId. The reason for this being that we may apply adjustments (coercions) with the resulting expression also needing to use the side tables. The problem with this is that we don't assign a separate NodeId to this new expression and so it would clash with the base expression if both needed to add to the side tables. Thus to disambiguate we also keep track of whether there's an adjustment in our key.
