Provided methods

fn get_packed_len() -> usize

Get the packed length

fn unpack(input: &[u8]) -> Result<Self, ProgramError> where
    Self: IsInitialized, 

Unpack from slice and check if initialized

fn unpack_unchecked(input: &[u8]) -> Result<Self, ProgramError>

Unpack from slice without checking if initialized

fn unpack_mut<F, U>(input: &mut [u8], f: &mut F) -> Result<U, ProgramError> where
    F: FnMut(&mut Self) -> Result<U, ProgramError>,
    Self: IsInitialized, 

Borrow Self from input for the duration of the call to f, but first check that Self is initialized

fn unpack_unchecked_mut<F, U>(
    input: &mut [u8],
    f: &mut F
) -> Result<U, ProgramError> where
    F: FnMut(&mut Self) -> Result<U, ProgramError>, 

Borrow Self from input for the duration of the call to f, without checking that Self has been initialized
