Enum IssueCode

    EmptyWorkflowId,
    EmptyWorkflowName,

    MissingStepId,
    DuplicateStepId,
    EmptyGroup,
    GroupTooDeep,
    MissingFunction,

Why a workflow definition is not loadable.

#[non_exhaustive]: a later minor may add a rule, and a host matching on the codes it cares about should keep compiling. Use Self::as_str to serialize.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyWorkflowId

id is missing or empty.

EmptyWorkflowName

name is missing or empty.

NoTasks

tasks is missing, not an array, or empty.

MissingStepId

A step carries no id.

DuplicateStepId

Two steps share an id. Groups share the task id namespace.

EmptyGroup

A group’s tasks is not a non-empty array.

GroupTooDeep

A group is nested at or beyond MAX_GROUP_DEPTH.

MissingFunction

A task carries no function.

InvalidFunctionName

function is not an object, or its name is missing or empty.

InvalidTerminal

terminal is present but not a boolean.

LoopIncrementTooSmall

loop.increment is below 1 — the counter would never reach max.

LoopBoundEmpty

loop.max is not greater than loop.init — no sweep could ever run.

LoopCounterInvalid

loop.counter is not a non-empty dotted path.

UnknownFunction

No handler will dispatch this function name, and it is not a built-in. Usually a typo or a handler the host forgot to register.

MissingHandler

The name is a built-in, but one that ships as a config schema only (http_call, enrich, publish_kafka) and no handler is registered under it. The workflow builds cleanly and then fails every message.

InputParse

A custom task’s input does not deserialize into its handler’s declared Input type.

TemplateCompile

A Template field of a custom task’s input does not compile.

ParseFailed

The document does not deserialize into a Workflow. Carries the parser’s own message, which names the offending field and type.

ValidateFailed

The document parses but Workflow::validate rejects it. A backstop: reaching this means a rule exists that the checks above do not model.
