class juturna.payloads.Draft(payload_type: T, copy_from: T | None = None)

Bases: Generic

Payloads can be built using drafts. A draft stores the payload values, and once it is compiled an actual payload will be generated.

clear()

Clear all stored keys and values

compile() → T

Compile the payload, using all the stored key-value items.

Returns:

A new payload.

Return type:

BasePayload

Raises:

TypeError – If the draft was not open, so the payload type was not set, the method raises a TypeError.
