Trait Pack

pub trait Pack: Sealed {
    const LEN: usize;

    // Provided methods
    fn get_packed_len() -> usize { ... }
    fn unpack(input: &[u8]) -> Result<Self, ProgramError>
       where Self: IsInitialized { ... }
    fn unpack_unchecked(input: &[u8]) -> Result<Self, ProgramError> { ... }
    fn pack(src: Self, dst: &mut [u8]) -> Result<(), ProgramError> { ... }
}

Safely and efficiently (de)serialize account state

Required Associated Constants

const LEN: usize

The length, in bytes, of the packed representation

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 pack(src: Self, dst: &mut [u8]) -> Result<(), ProgramError>

Pack into slice

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
