# rsa-l0-rust-approximant

The groupant beside prag/src/rsa.rs.groupant/rust_approximant.rs in the Mova repository: what the code computes, what it never does, how to go back from its outputs, its invariants, cost and checks.

## Facts

- **kind:** groupant
- **status:** bounded verified
- **source:** [`prag/src/rsa.rs.groupant/rust_approximant.rs`](https://github.com/ElamurAI/mova-free/blob/main/prag/src/rsa.rs.groupant/rust_approximant.rs)
- **source SHA-256:** `74e3c19640fce2f8…`

- **repository folder:** [`prag/src/rsa.rs.groupant/rust_approximant.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/prag/src/rsa.rs.groupant/rust_approximant.rs.groupant)
- **repository commit:** `855da7bd4a7b`

> **Implementation material.** A Mova code model describes this code at one source revision: partial models, finite checks and their stated scope. It is not a reviewed general exposition, and its labels are shown as written, never raised.

## Components

| component | label | where |
|---|---|---|
| **approximant** | partial | `../model.md` |
| **ast** | partial | `syntax.json` |
| **composition** | partial | `../model.md` |
| **cost** | partial | `../model.md` |
| **descriptant** | present | `../model.md` |
| **invariant** | partial | `../model.md` |
| **tests** | bounded execution | `../model.md#measurements` |

## Obernants

The typed relations around the forward model: the behaviour complement (what the code never does), the reverse reconstruction (every input compatible with an output) and specialised views.

| id | type | label | where |
|---|---|---|---|
| `nonbehavior` | behavior_complement | partial | `../model.md` |
| `antecedents` | reverse_reconstruction | partial | `../model.md` |
