Function pod_from_bytes_mut 

pub fn pod_from_bytes_mut<T>(data: &mut [u8]) -> Result<&mut T, ProgramError>
where
    T: Pod + FixedLayout,

Zero-copy cast from bytes to a mutable reference.

Safety

The returned reference aliases the input slice mutably. Callers must not create overlapping references (mutable or immutable) to the same memory.
