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.

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.
