Struct ChangeSetStack 

pub struct ChangeSetStack { /* private fields */ }

Implementations

impl ChangeSetStack

pub fn current_mut(&mut self) -> &mut EntityChangeSet

pub fn current(&self) -> Option<&EntityChangeSet>

pub fn push(&mut self)

pub fn pop(&mut self) -> Option<EntityChangeSet>

pub fn get(&self, key: &EntityKey, field: &str) -> Option<Value>

pub fn set(&mut self, key: EntityKey, field: impl Into<String>, value: Value)

pub fn clear_current(&mut self)

pub fn clear_entity(&mut self, key: &EntityKey)

Remove all pending changes for a specific entity key across all stack levels.

pub fn changed_field_names(&self, key: &EntityKey) -> BTreeSet<String>

Get the union of all changed field names for a given entity key across all stack levels. This is the Rust equivalent of Java’s entity.getUpdatedProperties().

Trait Implementations

impl Clone for ChangeSetStack

fn clone(&self) -> ChangeSetStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeSetStack

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

Formats the value using the given formatter.

impl Default for ChangeSetStack

fn default() -> ChangeSetStack

Returns the “default value” for a type.

impl PartialEq for ChangeSetStack

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