Enum EntityComponentError

pub enum EntityComponentError {
    MissingComponent(ComponentId),
    AliasedMutability(ComponentId),
}

An error that occurs when dynamically retrieving components from an entity.

Variants

MissingComponent(ComponentId)

The component with the given ComponentId does not exist on the entity.

AliasedMutability(ComponentId)

The component with the given ComponentId was requested mutably more than once.

Trait Implementations

impl Clone for EntityComponentError

fn clone(&self) -> EntityComponentError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntityComponentError

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

Formats the value using the given formatter.

impl Display for EntityComponentError

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

Formats the value using the given formatter.

impl Error for EntityComponentError

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 EntityComponentError

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