Struct LeafMetadata 

pub struct LeafMetadata {
    pub crdt_type: CrdtType,
    pub hlc_timestamp: u64,
    pub version: u64,
    pub collection_id: [u8; 32],
    pub parent_id: Option<[u8; 32]>,
}

Metadata for a leaf entity.

Minimal metadata needed for CRDT merge during sync.

This is a wire-protocol-optimized subset of calimero_storage::Metadata. It contains only the fields needed for sync operations, avoiding larger fields like field_name: String that aren’t needed over the wire.

When receiving entities, implementations should map this to/from the storage layer’s Metadata type.

Fields

crdt_type: CrdtType

CRDT type for proper merge semantics.

hlc_timestamp: u64

HLC timestamp of last modification.

version: u64

Version counter (for some CRDT types).

collection_id: [u8; 32]

Collection ID this entity belongs to.

parent_id: Option<[u8; 32]>

Optional parent entity ID (for nested structures).

Implementations

impl LeafMetadata

pub fn new( crdt_type: CrdtType, hlc_timestamp: u64, collection_id: [u8; 32], ) -> Self

Create metadata with required fields.

pub fn with_version(self, version: u64) -> Self

Set version.

pub fn with_parent(self, parent_id: [u8; 32]) -> Self

Set parent ID.

Trait Implementations

impl BorshDeserialize for LeafMetadata

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for LeafMetadata

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for LeafMetadata

fn clone(&self) -> LeafMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeafMetadata

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

Formats the value using the given formatter.

impl PartialEq for LeafMetadata

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