Function Documentation

bit_cast()

constexpr To std::bit_cast

(

From const &

from

)

Reinterpret the bit pattern content of an object (C++20) -.

C++20 Backports:

Reinterpret the bit pattern of an object as an object of a different type.

<bit>:

Reinterpret the bit pattern of a type.

Precondition

From , To need both to be trivially copyable.

In C++<14 in cxxomfort's implementation, To needs to also have a trivial default constructor.
