Enum Flow Error | NVIDIA NeMo Relay

Generated from cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-ffi.

pub enum FlowError {
    AlreadyExists(String),
    NotFound(String),
    InvalidArgument(String),
    ScopeStackEmpty,
    GuardrailRejected(String),
    Internal(String),
}

The error type for all NeMo Relay runtime operations.

Each variant represents a distinct failure mode that callers can match on to determine the appropriate recovery strategy.

Variants

`AlreadyExists(String)`

AlreadyExists(String)

A resource with the given name is already registered.

Returned when attempting to register a guardrail, intercept, or subscriber with a name that is already in use. Deregister the existing entry first, or choose a different name.

`NotFound(String)`

NotFound(String)

The requested resource was not found.

Returned when attempting to remove a scope handle by UUID that does not exist in the scope stack, or when looking up a non-existent entity.

`InvalidArgument(String)`

InvalidArgument(String)

A function argument was invalid for the requested operation.

Returned when a provided value is well-formed but violates an API precondition, such as attempting to pop a scope that is not currently at the top of the stack.

`ScopeStackEmpty`

ScopeStackEmpty

The scope stack is empty.

This should not occur under normal operation because the root scope is always present and cannot be removed.

`GuardrailRejected(String)`

GuardrailRejected(String)

A conditional execution guardrail rejected the operation.

The contained string is the rejection reason provided by the guardrail. This is returned during tool_call_execute or llm_call_execute when a conditional guardrail returns Some(reason).

`Internal(String)`

Internal(String)

An internal runtime error (e.g., lock poisoning).
