Implementations

impl Entity

pub fn new( uid: EntityUid, attrs: HashMap<String, RestrictedExpression>, parents: HashSet<EntityUid> ) -> Self

Create a new Entity with this Uid, attributes, and parents.

Attribute values are specified here as “restricted expressions”. See docs on RestrictedExpression

pub fn with_uid(uid: EntityUid) -> Self

Create a new Entity with this Uid, no attributes, and no parents.

pub fn uid(&self) -> EntityUid

Get the Uid of this entity

pub fn attr(&self, attr: &str) -> Option<Result<EvalResult, EvaluationError>>

Get the value for the given attribute, or None if not present.

This can also return Some(Err) if the attribute had an illegal value.

Trait Implementations

impl Clone for Entity

fn clone(&self) -> Entity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Entity

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

Formats the value using the given formatter.

impl Display for Entity

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

Formats the value using the given formatter.

impl PartialEq<Entity> for Entity

fn eq(&self, other: &Entity) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RefCast for Entity

type From = Entity

fn ref_cast(_from: &Self::From) -> &Self

fn ref_cast_mut(_from: &mut Self::From) -> &mut Self

impl Eq for Entity

impl StructuralEq for Entity
