Detailed Description

Describes the layout of a block of memory.

Layouts are passed to allocators, and consist of a (possibly padded) size and a power-of-two alignment no larger than the size. Layouts can be constructed for a type T using Layout::Of.

Example:

struct MyStruct {
  uint8_t field1[3];
  uint32_t field2[3];
};
constexpr Layout layout_for_struct = Layout::Of<MyStruct>();

If the result is okay, returns its contained layout; otherwise, returns a default layout.
