Struct UpdatePatch 

pub struct UpdatePatch { /* private fields */ }

UpdatePatch

Public structural mutation patch builder. Callers address fields by model field name and provide runtime Value payloads; validation remains model-owned and occurs both at patch construction and again during session mutation execution.

Implementations

impl UpdatePatch

pub const fn new() -> Self

Build one empty structural patch.

Callers then append field updates through set_field(...) so model field-name validation stays at the patch boundary.

pub fn set_field( self, model: &'static EntityModel, field_name: &str, value: Value, ) -> Result<Self, Error>

Resolve one model field name and append its structural field update.

This keeps the public patch surface field-name-driven while still validating field existence before mutation execution begins.

Trait Implementations

impl Default for UpdatePatch

fn default() -> UpdatePatch

Returns the “default value” for a type.
