A checkpoint frame header

Fields

checkpoint_id: u64

Unique checkpoint identifier

flags: u8

Frame flags

state_num: u64

State number this checkpoint represents

base_id: u64

Base checkpoint ID for incremental (0 if full)

uncompressed_size: u32

Uncompressed payload size

payload_len: u32

Actual payload size in frame

Implementations

impl CheckpointHeader

pub fn full(checkpoint_id: u64, state_num: u64, size: u32) -> Self

Create a full checkpoint header

pub fn incremental( checkpoint_id: u64, state_num: u64, base_id: u64, size: u32, ) -> Self

Create an incremental checkpoint header

pub fn is_compressed(&self) -> bool

Check if checkpoint is compressed

pub fn is_incremental(&self) -> bool

Check if checkpoint is incremental

pub fn is_signed(&self) -> bool

Check if checkpoint has signature

pub fn set_compressed(&mut self, compressed_len: u32)

Set compressed flag and actual payload size

pub fn set_signed(&mut self)

Set signed flag

pub fn encode(&self) -> [u8; 33]

Encode header to bytes

pub fn decode(data: &[u8]) -> Result<Self, NegotiationError>

Decode header from bytes

Trait Implementations

impl Clone for CheckpointHeader

fn clone(&self) -> CheckpointHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CheckpointHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CheckpointHeader

fn eq(&self, other: &CheckpointHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
