Extension methods for ASCII-subset only operations.

Types that can be “unsized” to a dynamically-sized type.

A marker trait for phantom variance types.

A trait for creating instances of `Hasher`.

A hashable type.

A trait for borrowing data.

Conversion into a `Future`.

The bitwise AND assignment operator `&=`.

The unary negation operator `-`.

The left 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.shl(b)` are one and the same from an evaluation standpoint, they are different when it comes to type inference.
