Implementations

impl EntityChangeSet

pub fn is_empty(&self) -> bool

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

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

pub fn changes(&self) -> &BTreeMap<EntityKey, Record>

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

Remove all pending changes for a specific entity key.

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

Get the set of field names that have been modified for a given entity key.

Trait Implementations

impl Clone for EntityChangeSet

fn clone(&self) -> EntityChangeSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityChangeSet

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

Formats the value using the given formatter.

impl Default for EntityChangeSet

fn default() -> EntityChangeSet

Returns the “default value” for a type.

impl PartialEq for EntityChangeSet

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