## Sub-dependencies with `yield`

You can have sub-dependencies and "trees" of sub-dependencies of any size and shape, and any or all of them can use `yield`.

**FastAPI** will make sure that the "exit code" in each dependency with `yield` is run in the correct order.

// the object values are emitted.
func (d *Decoder) EmitKV() *Decoder {
	d.emitKV = true
	return d
}

// Recursive enables emitting all values at a depth higher than the
// configured emit depth; e.g. if an array is found at emit depth, all
// values within the array are emitted to the stream, then the array
// containing those values is emitted.
func (d *Decoder) Recursive() *Decoder {
	d.emitRecursive = true

Das ist nützlich, wenn Sie die gültigen Feld-/Attribut-Namen von vorneherein nicht wissen (was für ein Pydantic-Modell notwendig ist).

In diesem Fall können Sie `typing.Dict` verwenden (oder nur `dict` in Python 3.9 und darüber):
