Struct CheckpointHeader 

pub struct CheckpointHeader {
    pub version: [u32; 3],
    pub timestamp: u64,
    pub step: u64,
    pub crate_name: String,
    pub checksum: u32,
}

Header record written at the top of every checkpoint file.

Fields

version: [u32; 3]

File format version [major, minor, patch].

timestamp: u64

Unix timestamp (seconds) of when the checkpoint was written.

step: u64

Simulation step number.

crate_name: String

Producing crate name.

checksum: u32

CRC32 checksum of the payload that follows.

Implementations

impl CheckpointHeader

pub fn new( version: [u32; 3], timestamp: u64, step: u64, crate_name: impl Into<String>, checksum: u32, ) -> Self

Create a new CheckpointHeader.

pub fn to_bytes(&self) -> Vec<u8>

Serialise to bytes.

pub fn from_bytes(data: &[u8]) -> Result<Self>

Deserialise from bytes.

pub fn version_compatible(&self, expected_major: u32) -> bool

Return true if this header’s major version matches expected.

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.
