Struct UpdatePatch 

pub struct UpdatePatch { /* private fields */ }

UpdatePatch

UpdatePatch

UpdatePatch is the ordered structural mutation program applied to one persisted row. This is the phase-1 0.64 patch container: it updates slot values structurally and then re-encodes the full row.

Implementations

impl UpdatePatch

pub const fn new() -> Self

Build one empty patch.

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

Resolve one field name and append its structural update.

Trait Implementations

impl Clone for UpdatePatch

fn clone(&self) -> UpdatePatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdatePatch

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

Formats the value using the given formatter.

impl Default for UpdatePatch

fn default() -> UpdatePatch

Returns the “default value” for a type.

impl PartialEq for UpdatePatch

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