Enum bevy_defer::AccessError

#[non_exhaustive]
pub enum AccessError {
    ChannelClosed,
    EntityNotFound,
    TooManyEntities,
    ChildNotFound,
    ComponentNotFound,
    ResourceNotFound,
    AssetNotFound,
    EventNotRegistered,
    SignalNotFound,
    ScheduleNotFound,
    SystemParamError,
    WorldParamNotFound,
    SystemIdNotFound,
    NameNotFound,
    IO,
    Custom,
    ShouldNotHappen,
}

Standard errors for the async runtime.

This type is designed to be match friendly but not necessarily carry all the debugging information. It might me more correct to either match or unwrap this error instead of propagating it.

Logging Pattern

For custom errors, convert to AccessError via Into and log the message via bevy_log in the into implementation.

returns_a_custom_error().await?;

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl AccessError

pub fn with_message(&self, e: impl Error) -> CustomError

Create a CustomError with a message.

pub fn with_message_static(&self, e: &'static str) -> CustomError

Create a CustomError with a static string message.

Trait Implementations

impl Clone for AccessError

fn clone(&self) -> AccessError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccessError

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

Formats the value using the given formatter.

impl Display for AccessError

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

Formats the value using the given formatter.

impl Error for AccessError

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

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<CustomError> for AccessError

fn from(val: CustomError) -> Self

Converts to this type from the input type.

impl PartialEq for AccessError

fn eq(&self, other: &AccessError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
