A marker trait which represents “panic safe” types in Rust.

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.

A specialized `Result` type for threads.

A marker trait representing types where a shared reference is considered unwind safe.

Creates a scope for spawning scoped threads.

A value-to-value conversion that consumes the input value. The opposite of `From`.

Used to tell an operation whether it should exit early or go on as usual.

The Math.log() static method returns the natural logarithm (base e) of a number. That is

An iterator that decodes UTF-16 encoded code points from an iterator of `u16`s.

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