Struct EntityRef 

pub struct EntityRef {
    pub type_name: String,
    pub display: String,
    /* private fields */
}

Reference to an entity involved in a constraint match.

Uses type erasure to allow storing references to different entity types in a single collection.

Fields

type_name: String

Type name of the entity (e.g., “Shift”, “Employee”).

display: String

String representation for display.

Implementations

impl EntityRef

pub fn new<T: Clone + Debug + Send + Sync + 'static>(entity: &T) -> Self

Creates a new entity reference from a concrete entity.

pub fn with_display<T: Clone + Send + Sync + 'static>( entity: &T, display: String, ) -> Self

Creates an entity reference with a custom display string.

pub fn as_entity<T: 'static>(&self) -> Option<&T>

Attempts to downcast to the concrete entity type.

pub fn short_type_name(&self) -> &str

Returns the short type name (without module path).

Trait Implementations

impl Clone for EntityRef

fn clone(&self) -> EntityRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityRef

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

Formats the value using the given formatter.

impl Hash for EntityRef

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EntityRef

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