Enum RegisteredSystemError

pub enum RegisteredSystemError<I: SystemInput = (), O = ()> {
    SystemIdNotRegistered(SystemId<I, O>),
    SystemNotCached,
    Recursive(SystemId<I, O>),
    SelfRemove(SystemId<I, O>),
    Skipped(SystemParamValidationError),
    Failed(BevyError),
    IncorrectType(SystemId<I, O>, SystemIdMarker),
}

An operation with stored systems failed.

Variants

SystemIdNotRegistered(SystemId<I, O>)

A system was run by id, but no system with that id was found.

Did you forget to register it?

SystemNotCached

A cached system was removed by value, but no system with its type was found.

Did you forget to register it?

Recursive(SystemId<I, O>)

A system tried to run itself recursively.

SelfRemove(SystemId<I, O>)

A system tried to remove itself.

Skipped(SystemParamValidationError)

System could not be run due to parameters that failed validation. This is not considered an error.

Failed(BevyError)

System returned an error or failed required parameter validation.

IncorrectType(SystemId<I, O>, SystemIdMarker)

SystemId had different input and/or output types than SystemIdMarker

Trait Implementations

impl<I: SystemInput, O> Error for RegisteredSystemError<I, O>

where Self: Debug + Display,

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

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<I: SystemInput, O> From<RunSystemError> for RegisteredSystemError<I, O>

fn from(value: RunSystemError) -> Self
