Struct SyncPatch 

pub struct SyncPatch {
    pub source_node: NodeId,
    pub entries: Vec<PatchEntry>,
    pub crdt_aware: bool,
}

A serializable sync patch containing entries to apply to a target database.

Fields

source_node: NodeId

entries: Vec<PatchEntry>

crdt_aware: bool

Implementations

impl SyncPatch

pub fn from_diff( source_node: NodeId, diff: &DiffResult, crdt_aware: bool, ) -> Self

Build a SyncPatch from a DiffResult.

If crdt_aware is true, values are expected to contain CRDT headers and entries will carry CrdtMeta extracted from the value prefix.

pub fn empty(source_node: NodeId) -> Self

Create an empty patch.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

Serialize to binary wire format.

Format:

[magic: u32 LE][version: u8][flags: u8][source_node: 8B][entry_count: u32 LE]
Per entry:
  [key_len: u16 LE][value_len: u32 LE][kind: u8]
  [crdt_meta: 20B]  (if FLAG_HAS_CRDT)
  [key: key_len bytes][value: value_len bytes]

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

Deserialize from binary wire format.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for SyncPatch

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