Enum ComponentError 

pub enum ComponentError {
    NoSuchEntity,
    MissingComponent(MissingComponent),
}

Errors that arise when accessing components

Variants

NoSuchEntity

The entity was already despawned

MissingComponent(MissingComponent)

The entity did not have a requested component

Trait Implementations

impl Clone for ComponentError

fn clone(&self) -> ComponentError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentError

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

Formats the value using the given formatter.

impl Display for ComponentError

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

Formats the value using the given formatter.

impl Eq for ComponentError

impl Error for ComponentError

Available on crate feature std only.

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<MissingComponent> for ComponentError

fn from(x: MissingComponent) -> ComponentError

Converts to this type from the input type.

impl From<NoSuchEntity> for ComponentError

fn from(_: NoSuchEntity) -> ComponentError

Converts to this type from the input type.

impl Hash for ComponentError

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ComponentError

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