Bind by reference during pattern matching.

A wrapper for `&[u8]` representing a human-readable string that’s conventionally, but not always, UTF-8.

Required trait for constants used in pattern matches.

The right shift operator `>>`. Note that because this trait is implemented for all integer types with multiple right-hand-side types, Rust’s type checker has special handling for `_ >> _`, setting the result type for integer operations to the type of the left-hand-side operand. This means that though `a >> b` and `a.shr(b)` are one and the same from an evaluation standpoint, they are different when it comes to type inference.

A trait to emulate dynamic typing.

A hash set implemented as a `HashMap` where the value is `()`.

A wrapper type for a mutably borrowed value from a `RefCell<T>`.

A marker for pointer-like types.

`DispatchFromDyn` is used in the implementation of dyn-compatibility checks (specifically allowing arbitrary self types), to guarantee that a method’s receiver type can be dispatched on.

Trait that indicates that this is a pointer or a wrapper for one, where unsizing can be performed on the pointee.
