Fields

binding_mode: BindingMode

Is variable bound via x, mut x, ref x, or ref mut x?

opt_ty_info: Option<Span>

If an explicit type was provided for this variable binding, this holds the source Span of that type.

NOTE: if you want to change this to a HirId, be wary that doing so breaks incremental compilation (as of this writing), while a Span does not cause our tests to fail.

opt_match_place: Option<(Option<Place<'tcx>>, Span)>

Place of the RHS of the =, or the subject of the match where this variable is initialized. None in the case of let PATTERN;. Some((None, ..)) in the case of and let [mut] x = ... because (a) the right-hand side isn’t evaluated as a place expression. (b) it gives a way to separate this case from the remaining cases for diagnostics.

pat_span: Span

The span of the pattern in which this variable was bound.
