Errors that can occur during graph operations

Variants

InvalidGraph(String)

Graph structure is invalid

NodeNotFound(String)

Node not found

EdgeTargetNotFound(String)

Edge target not found

NoEntryPoint

No entry point defined

RecursionLimitExceeded(usize)

Recursion limit exceeded

Interrupted(Box<InterruptedExecution>)

Execution was interrupted

NodeExecutionFailed

Node execution failed

Fields

node: String

message: String

NodeTimedOut

Node timed out

Fields

node: String

elapsed: Duration

FanInTimedOut

Fan-in node timed out waiting for upstream paths

Fields

node: String

received: usize

expected: usize

SerializationError(String)

State serialization error

CheckpointError(String)

Checkpoint error

UndeclaredChannel

A node wrote a channel the state schema does not declare.

Only raised when channel enforcement is on. An undeclared channel otherwise takes the overwrite reducer, which silently discards the appends a list channel was meant to collect.

Fields

node: String

The node that produced the update.

channel: String

The channel name that is not declared.

SubgraphChannelMismatch

A subgraph mapping names a channel the relevant side does not declare.

Fields

subgraph: String

The subgraph node’s name.

channel: String

The channel that is not declared.

side: String

Which side is missing it, the parent or the subgraph.

UnknownRouteTarget(String)

Router returned unknown target

IoError(Error)

IO error

JsonError(Error)

JSON error

Other(String)

Other error (used by extensions like the functional API)

Trait Implementations

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Error for GraphError

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<Error> for GraphError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for GraphError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<GraphError> for AdkError

fn from(err: GraphError) -> Self

Converts to this type from the input type.
