Implementations

impl SyncActionCodec

pub const fn carries_node_keys(self) -> bool

Returns whether this action carries registered node-key arguments.

Insert and remove-overlay actions reference source/target node keys; the others carry dense ids or nothing. Both Self::decode_wire and the dense-map key harvest consult this so the keyed-action set lives in one place instead of being a magic literal pair.

Performance

This method is O(1).

pub fn decode_wire( action_type: i16, arg0: Option<i64>, arg1: Option<i64>, ) -> Result<SyncActionWire, SyncError>

Decodes a persisted sync row into a wire action.

Errors

Returns SyncError when the action type or arguments are invalid.

Performance

This method is O(1).

pub fn decode( action_type: i16, arg0: Option<i64>, arg1: Option<i64>, node_map: &BTreeMap<NodeKey, u32>, ) -> Result<SyncAction, SyncError>

Decodes a persisted sync row into a dense SyncAction.

Keyed insert/remove actions require node_map built from the current relational edge scan.

Errors

Returns SyncError when decoding or dense resolution fails.

Performance

This method is O(1) per row excluding map lookup.

Trait Implementations

impl Clone for SyncActionCodec

fn clone(&self) -> SyncActionCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncActionCodec

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

Formats the value using the given formatter.

impl PartialEq for SyncActionCodec

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

impl TryFrom<i16> for SyncActionCodec

fn try_from(value: i16) -> Result<Self, Self::Error>

Maps a persisted action-type id to its codec variant.

Errors

Returns SyncError::InvalidActionType for an unknown id.

Performance

This function is O(1).

type Error = SyncError

The type returned in the event of a conversion error.
