Enum EntityMutableFetchError

pub enum EntityMutableFetchError {
    EntityDoesNotExist(EntityDoesNotExistError),
    AliasedMutability(Entity),
}

Trait Implementations

impl Clone for EntityMutableFetchError

fn clone(&self) -> EntityMutableFetchError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntityMutableFetchError

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

Formats the value using the given formatter.

impl Display for EntityMutableFetchError

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

Formats the value using the given formatter.

impl Error for EntityMutableFetchError

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 From<EntityDoesNotExistError> for EntityMutableFetchError

fn from(source: EntityDoesNotExistError) -> EntityMutableFetchError

Converts to this type from the input type.

impl<E> From<EntityMutableFetchError> for EntityCommandError<E>

fn from(source: EntityMutableFetchError) -> EntityCommandError<E>

Converts to this type from the input type.

impl From<EntityMutableFetchError> for EntityDespawnError

fn from(source: EntityMutableFetchError) -> EntityDespawnError

Converts to this type from the input type.

impl PartialEq for EntityMutableFetchError

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