Source 
pub struct ExprUseCtxt<'tcx> {
    pub node: Node<'tcx>,
    pub child_id: HirId,
    pub adjustments: &'tcx [Adjustment<'tcx>],
    pub is_ty_unified: bool,

Expand description

The context an expressions value is used in.

Fields§

§node: Node<'tcx>

The parent node which consumes the value.

§child_id: HirId

The child id of the node the value came from.

§adjustments: &'tcx [Adjustment<'tcx>]

Any adjustments applied to the type.

§is_ty_unified: bool

Whether the type must unify with another code path.

§moved_before_use: bool

Whether the value will be moved before it’s used.

§same_ctxt: bool

Whether the use site has the same SyntaxContext as the value.
