# [−][src]Function core::intrinsics::size_of

    pub unsafe extern "rust-intrinsic" fn size_of<T>() -> usize

🔬 This is a nightly-only experimental API. (`core_intrinsics` #0)

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.

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 `std::mem::size_of`.
