Enum WorldError 

pub enum WorldError {
    EntityNotFound(EntityId),
    ComponentNotFound {
        entity_id: EntityId,
        component_name: &'static str,
    },
    PartialRemoval {
        succeeded: Vec<EntityId>,
        failed: Vec<EntityId>,
    },
    // some variants omitted
}

Errors that can occur when interacting with the World.

Variants

EntityNotFound(EntityId)

The specified entity was not found in the world.

ComponentNotFound

The requested component type was not found on the entity.

Fields

entity_id: EntityId

component_name: &'static str

PartialRemoval

Batch removal completed with some failures. Contains the list of successfully removed entities and failed entities.

Fields

succeeded: Vec<EntityId>

failed: Vec<EntityId>

Trait Implementations

impl Clone for WorldError

fn clone(&self) -> WorldError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorldError

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

Formats the value using the given formatter.

impl Display for WorldError

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

Formats the value using the given formatter.

impl Error for WorldError

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 WorldError

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