Enum EffectOrderError 

pub enum EffectOrderError {
    TooManyCompleted,
    DuplicateCompleted(u64),
    UnmetDependency {
        operation_sequence: u64,
        dependency: u64,
    },
    Graph(EffectGraphError),
}

Typed declared progress inconsistency, before scheduling or effects.

Variants

TooManyCompleted

Declared completed list exceeds the maintained graph bound.

DuplicateCompleted(u64)

One exact operation is declared completed more than once.

UnmetDependency

A declared completed operation lacks a declared completed prerequisite.

Fields

operation_sequence: u64

Exact declared completed operation.

dependency: u64

Missing declared completed prerequisite.

Graph(EffectGraphError)

Exact operation identity is absent from its owning graph.

Trait Implementations

impl Debug for EffectOrderError

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

Formats the value using the given formatter.

impl Display for EffectOrderError

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

Formats the value using the given formatter.

impl Error for EffectOrderError

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<EffectGraphError> for EffectOrderError

fn from(source: EffectGraphError) -> Self

Converts to this type from the input type.
