pub struct BindingMode(pub ByRef, pub Mutability);
Expand description
The mode of a binding (mut
, ref mut
, etc).
Used for both the explicit binding annotations given in the HIR for a binding
and the final binding mode that we infer after type inference/match ergonomics.
.0
is the by-reference mode (ref
, ref mut
, or by value),
.1
is the mutability of the binding.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
