String slices.

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 contiguous growable array type, written as `Vec<T>`, short for ‘vector’.

A UTF-8–encoded, growable string.

A trait for dealing with iterators.

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.

A dynamically-sized view into a contiguous sequence, `[T]`. Contiguous here means that elements are laid out so that every element is the same distance from its neighbors.

A pointer type that uniquely owns a heap allocation of type `T`.
