Enum SimulationBuildError 

pub enum SimulationBuildError {
    DuplicateEntityId(EntityId),
    EventReferencesUnknownEntity(EventId, EntityId),
    RelationshipReferencesUnknownEntity(RelationshipId, EntityId),
    SelfRelationship(EntityId),
}

Error type for simulation build failures.

Variants

DuplicateEntityId(EntityId)

An entity was added with a duplicate ID.

EventReferencesUnknownEntity(EventId, EntityId)

An event references an entity that doesn’t exist in the simulation. Contains the event ID and the unknown entity ID.

RelationshipReferencesUnknownEntity(RelationshipId, EntityId)

A relationship references an entity that doesn’t exist in the simulation. Contains the relationship ID and the unknown entity ID.

SelfRelationship(EntityId)

A relationship between an entity and itself was attempted.

Trait Implementations

impl Clone for SimulationBuildError

fn clone(&self) -> SimulationBuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimulationBuildError

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

Formats the value using the given formatter.

impl Display for SimulationBuildError

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

Formats the value using the given formatter.

impl Error for SimulationBuildError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for SimulationBuildError

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