Expand description

The size of a type in bytes.

Note that, unlike most intrinsics, this is safe to call; it does not require an unsafe block. Therefore, implementations must not require the user to uphold any safety invariants.

More specifically, this is the offset in bytes between successive items of the same type, including alignment padding.

The stabilized version of this intrinsic is core::mem::size_of.
