}

Typed declared graph identity, dependency or resource-bound rejection.

Variants

UnsupportedVersion(u16)

Only protocol generation v1 is maintained.

EmptyGraph

At least one exact operation must be declared.

TooManyOperations

Node count exceeds its maintained bound.

TooManyDependencies

One operation declares too many direct dependencies.

TooManyEdges

Total graph dependencies exceed the maintained bound.

DuplicateOperation(u64)

An exact operation was declared more than once.

UnknownOperation(u64)

A requested exact operation is absent.

DuplicateDependency

A dependency identity appears more than once in one operation.

Fields

operation_sequence: u64

Exact owning operation sequence.

dependency: u64

Repeated exact prerequisite sequence.

MissingDependency

An edge references an absent exact operation.

Fields

operation_sequence: u64

Exact owning operation sequence.

dependency: u64

Absent prerequisite sequence.

Cycle

Dependencies include a self-loop or longer cycle.

Trait Implementations

impl Debug for EffectGraphError

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

Formats the value using the given formatter.

impl Display for EffectGraphError

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

Formats the value using the given formatter.

impl Error for EffectGraphError

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.
