Function ptah::serialized_size

pub fn serialized_size<T>(value: &T) -> Result<usize> where
    T: Serialize, 

It can sometimes be useful to know the size of a value in its serialized form (e.g. to reserve space for it in a ring buffer). This calculates the number of bytes taken to serialize some value of T into Ptah's wire format. Note that this size is for the specific value, and may differ between values of T.
