Description: The size of a type in bytes.
Keywords: rust, rustlang, rust-lang, size_of

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

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

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

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Expand description

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 `core::mem::size_of`.
