Function std::intrinsics::size_of
pub const extern "rust-intrinsic" fn size_of<T>() -> usize
core_intrinsics)intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
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.
