Struct SyncItem 

pub struct SyncItem {
    pub cid: String,
    pub checksum: u64,
    pub size_bytes: u64,
    pub version: u64,
    pub last_modified: u64,
    pub mirror_id: MirrorId,
}

A single item tracked for synchronisation across mirrors.

Fields

cid: String

Content Identifier (CID) of the block.

checksum: u64

FNV-1a-64 checksum of the CID bytes.

size_bytes: u64

Block size in bytes.

version: u64

Monotonically increasing version number.

last_modified: u64

UNIX timestamp (ms) of the last modification.

mirror_id: MirrorId

The mirror that owns / sourced this item.

Implementations

impl SyncItem

pub fn new( cid: String, size_bytes: u64, last_modified: u64, mirror_id: MirrorId, ) -> Self

Creates a SyncItem, computing the FNV-1a-64 checksum from the CID bytes.

pub fn with_version( cid: String, size_bytes: u64, version: u64, last_modified: u64, mirror_id: MirrorId, ) -> Self

Creates a SyncItem with all fields specified explicitly.

pub fn with_checksum( cid: String, checksum: u64, size_bytes: u64, version: u64, last_modified: u64, mirror_id: MirrorId, ) -> Self

Creates a SyncItem with an explicitly provided checksum (for testing / deserialization).

Trait Implementations

impl Clone for SyncItem

fn clone(&self) -> SyncItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncItem

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

Formats the value using the given formatter.

impl Eq for SyncItem

impl PartialEq for SyncItem

fn eq(&self, other: &SyncItem) -> 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.
