A 64-bit floating-point type (specifically, the “binary64” type defined in IEEE 754-2008).

The `ByteStr` and `ByteString` types and trait implementations.

A module for working with processes.

Utilities for the `char` primitive type.

Redundant constants module for the `i16` primitive type.

An integer type which can be safely shared between threads.

An `AtomicBool` initialized to `false`.

A raw pointer type which can be safely shared between threads.

A captured OS thread stack backtrace.

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.
