`DispatchFromDyn` is used in the implementation of dyn-compatibility checks (specifically allowing arbitrary self types), to guarantee that a method’s receiver type can be dispatched on.

`Request` supports generic, type-driven access to data. Its use is currently restricted to the standard library in cases where trait authors wish to allow trait implementors to share generic information across trait boundaries. The motivating and prototypical use case is `core::error::Error` which would otherwise require a method per concrete type (eg. `std::backtrace::Backtrace` instance that implementors want to expose to users).

Trait that indicates that this is a pointer or a wrapper for one, where unsizing can be performed on the pointee when it is pinned.

Compares and returns the maximum of two values.

One greater than the minimum possible normal power of 2 exponent. Use `f32::MIN_EXP` instead.

Derive macro generating an impl of the trait `Default`.

Returns the element that gives the minimum value from the specified function.

Derive macro generating an impl of the trait `Eq`. The behavior of this macro is described in detail here.

A helper struct for reverse ordering.
