Plan

Defined in: plan/plan.ts:52

Compiled, immutable execution plan.

Created by Planner.compile(). Execute with run(plan, ctx).

The Plan is immutable and can be reused across multiple executions. It contains:

• The AST defining the computation graph
• Injectors mapping emit nodes to their runtime behavior

Example

const plan = new Planner()
  .in(load({ name: 'test' }))
  .emit((out, $) => out.add('result', $.get('name').string()))
  .compile()

// Plan can be executed multiple times
const result1 = await run(plan)
const result2 = await run(plan)

Type Parameters

Out

Out

The output type this plan produces
