    },

Reason a workflow invocation was rejected by the guard.

Each variant carries the observed value and the configured limit for diagnostics.

Examples

use ironflow_engine::guard::WorkflowRejection;

let r = WorkflowRejection::MaxDepthExceeded { depth: 6, max: 5 };
assert!(r.to_string().contains("6"));
assert!(r.to_string().contains("5"));

Variants

MaxDepthExceeded

The sub-workflow nesting depth exceeds the configured maximum.

Fields

depth: u32

Current depth.

max: u32

Configured limit.

CycleDetected

The target workflow is already in the call chain (direct or indirect cycle).

Fields

target: String

The workflow that would create a cycle.

chain: Vec<String>

The current call chain.

MaxFanOutExceeded

The total number of workflow invocations exceeds the configured maximum.

Fields

invocations: u32

Current invocation count.

max: u32

Configured limit.

TokenBudgetExhausted

The cumulative token usage exceeds the configured budget.

Fields

used: u64

Tokens already consumed.

max: u64

Configured limit.

WorkflowTimeout

The workflow has exceeded its global timeout.

Fields

elapsed_secs: u64

Seconds elapsed since the workflow started.

max: u64

Configured limit.

GuardUnavailable

The guard state is unavailable (fail closed).

Trait Implementations

impl Clone for WorkflowRejection

fn clone(&self) -> WorkflowRejection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorkflowRejection

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

impl Eq for WorkflowRejection

impl Error for WorkflowRejection

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<WorkflowRejection> for EngineError

fn from(source: WorkflowRejection) -> Self

Converts to this type from the input type.

impl PartialEq for WorkflowRejection

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

Equality operator ==.

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

Inequality operator !=.
