        compiled_input: Option<CompiledCustomInput>,
    },
}

Enum containing all possible function configurations.

Deserialization dispatches on the name field: each known built-in (map, validate, parse_json, …) parses its input strictly into the matching typed config and errors with a clear envelope (config for function 'map': missing field 'mappings'). Unknown names fall through to FunctionConfig::Custom, which preserves the raw input for a user-registered handler to consume at engine construction time.

Variants

Map

Fields

name: MapName

input: MapConfig

Validation

Fields

name: ValidationName

input: ValidationConfig

ParseJson

Fields

name: ParseJsonName

input: ParseConfig

ParseXml

Fields

name: ParseXmlName

input: ParseConfig

PublishJson

Fields

name: PublishJsonName

input: PublishConfig

PublishXml

Fields

name: PublishXmlName

input: PublishConfig

Filter

Fields

name: FilterName

input: FilterConfig

Log

Fields

name: LogName

input: LogConfig

HttpCall

Fields

name: HttpCallName

input: HttpCallConfig

Enrich

Fields

name: EnrichName

input: EnrichConfig

PublishKafka

Fields

name: PublishKafkaName

input: PublishKafkaConfig

Custom

For custom or unknown functions, store raw input and a slot for the pre-parsed typed value populated at engine construction time.

Fields

name: String

input: Value

compiled_input: Option<CompiledCustomInput>

Pre-parsed <RegisteredHandler as AsyncFunctionHandler>::Input, boxed as dyn Any. Set by the engine after handler registration; None on initial deserialization. FunctionConfig is deserialize-only — round-tripping a workflow through JSON re-parses on the next Engine::new() call.

Implementations

impl FunctionConfig

pub fn function_name(&self) -> &str

Get the function name for this configuration

pub fn is_sync_builtin(&self) -> bool

Whether this is a synchronous built-in. Synchronous built-ins can share a single ArenaContext lifetime across consecutive tasks within a workflow without crossing any .await point.

Must match the variants handled in Self::try_execute_in_arena; the debug assertion below ties the two together so they can’t drift.

Trait Implementations

impl Clone for FunctionConfig

fn clone(&self) -> FunctionConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionConfig

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
