Function core::mem::size_of_val
1.0.0 (const: unstable) · source · pub fn size_of_val<T: ?Sized>(val: &T) -> usizeExpand description
Returns the size of the pointed-to value in bytes.
This is usually the same as size_of::<T>(). However, when T has no
statically-known size, e.g., a slice [T] or a trait object,
then size_of_val can be used to get the dynamically-known size.
