Converts a `u32` to a `char`. Use `char::from_u32` instead.

Constructs I/O objects from raw handles.

Creates an iterator which, starting from an initial item, computes each successive item from the preceding one.

Used to determine whether a type contains any `UnsafeCell` internally, but not through an indirection. This affects, for example, whether a `static` of that type is placed in read-only static memory or writable static memory. This can be used to declare that a constant with a generic type will not contain interior mutability, and subsequently allow placing the constant behind references.

An error returned from the `Sender::send` or `SyncSender::send` function on channels.

Creates a new synchronous, bounded channel.

This enumeration is the list of the possible error outcomes for the `try_send` method.

Creates a scope for spawning scoped threads.

Registers a function to run for every newly thread spawned.

A borrowed socket.
