Wrap a value and run a closure when dropped.

A TCP socket server, listening for connections.

A marker type which does not implement `Unpin`.

Provides intentionally-saturating arithmetic on `T`.

This is the error type used by `HandleOrNull` when attempting to convert into a handle, to indicate that the value is null.

The error type returned when a checked integral type conversion fails.

The version of the call operator that takes an immutable receiver.

Result of calling `Searcher::next()` or `ReverseSearcher::next_back()`.

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.

The remainder assignment operator `%=`.
