Struct UpdateOp 

pub struct UpdateOp { /* private fields */ }

Patches one record with a stage-time preimage of exactly the touched fields.

Patch and preimage must target the same substrate and have identical field presence; both construction and deserialization enforce this invariant. See crates/khive-changeset/docs/api/update.md for nullable-field semantics.

Implementations

impl UpdateOp

pub fn new( target_id: Id128, patch: UpdatePatch, preimage: UpdatePreimage, ) -> Result<Self, String>

Constructs an update after validating patch/preimage congruence.

Errors

Returns an error for differing substrates or field sets, or for an invalid captured salience, decay factor, or edge weight, or an invalid new edge weight.

pub fn target_id(&self) -> Id128

The identifier of the record this update targets.

pub fn patch(&self) -> &UpdatePatch

The staged patch.

pub fn preimage(&self) -> &UpdatePreimage

The field-scoped prior value the patch touches.
