Struct TransformConfig 

pub struct TransformConfig {
    pub input_from: Vec<String>,
    pub transform_fn: TransformFn,
    pub async_fn: Option<AsyncTransformFn>,
    pub script: Option<String>,
}

Configuration for a Transform node (pure function, async function, or external script).

Execution priority: script > async_fn > transform_fn.

Fields

input_from: Vec<String>

IDs of upstream nodes whose output is used as input.

transform_fn: TransformFn

The sync transform function (lowest priority fallback).

async_fn: Option<AsyncTransformFn>

Optional async transform function.

script: Option<String>

Optional external script path. When set, the runtime spawns the script as a subprocess, pipes input JSON via stdin, and captures output JSON from stdout. Supports: .mjs, .js (node), .py (python3), .sh (bash).
