Continuous validation

Maturity labels

  • Now: Stable and supported in current releases.
  • Preview: Usable today, but behavior and APIs may evolve.
  • Planned: Not yet implemented.

Note

Status: Now

1) What it solves

You parse data once, then keep working with it. Without continuous checks, later edits can silently break assumptions.

2) The idea

Model[T] parses input into T and continues enforcing that type as you mutate the object. Omnipy models also mimic the behavior of the wrapped type (for example, list methods).

3) Example

>>> import omnipy as om
>>> vals = om.Model[list[int]]((1, '2', 3.0))
>>> vals.append('4')
>>> vals

4) Output / display

╭──────────────────╮
│ Model[list[int]] │
│                  │
│ [1, 2, 3]        │
╰──────────────────╯

5) When to use / when not

Use it when data stays mutable across several steps (notebooks, scripts, small pipelines).

Skip it when you parse once and immediately serialize out without in-memory edits.

6) Gotchas

  • Continuous validation is independent from rollback behavior.
  • Rollback safety is controlled by runtime.config.data.model.interactive.
