A generalization of `Clone` to dynamically-sized types stored in arbitrary containers.

A trait for creating instances of `Hasher`.

API documentation for the Rust `AggregateRawPtr` trait in crate `std`.

An iterator that reports an accurate length using size_hint.

Marker trait for the types that are allowed in union fields, unsafe fields, and unsafe binder types.

An error returned from the `send_timeout` method.

A trait for borrowing data.

WASI-specific extensions to `fs::Metadata`.

Unix-specific extensions to the `process::Command` builder.

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.
