TypeSafe SDK Rust — codeitlikemiley
Unofficial Rust client for the TypeSafe AI System One API, matching the Python SDK 0.6.0 contract: named noul, choice and score questions, a typestated builder, per-call overrides, and a `wire` module for serving the same shape.

About this project
Rust client for the TypeSafe AI API. It matches the Python typesafe-sdk 0.6.0 contract. Callers send named questions and get typed answers. Read AGENTS.md before you write integration code. Copy from examples/systemone.rs. Requires Rust 1.85 or later. Edition 2024. This crate requires serdejson = "1.0.134", a minimum rather than a pin: any 1.x from 1.0.134 up works, so serdejson = "1" or cargo add serdejson is fine. It enables serdejson's preserveorder feature, which Cargo unifies into your build.

Highlights
- The builder is typestated, so `build()` only exists after `api_key(...)` and a missing key becomes a compile error rather than a runtime surprise.
- The `wire` module serves the same shape: unknown question types stay `Question::Raw` and unknown top-level keys stay in `extra` for a gateway.
- Default retries are two after the first attempt on 408, 429 and 5xx, backing off 0.5s to 5s with jitter inside a 30s budget, honoring `Retry-After`.
- Base URLs join by string concatenation, so a trailing `/v1` yields `/v1/v1/systemone`; `tests/contract.rs` locks the prefix pattern against a mock.
Watch out
Behavior targets `typesafe-sdk-python` 0.6.0 and OpenAPI 0.2.0, but the Rust crate has its own 0.2.0 version line and is not a version bump of that release; there is no `nouls` dict. It requires `serde_json` 1.0.134 or newer and enables `preserve_order` into your build. Live API calls are excluded from `cargo test`, and `cargo bench` only talks to an in-process wiremock. Copy reviewed against the repository README on 2026-10-04, not from running it.
Questions about this entry
Short answers drawn from the linked project or page.
Close on behavior, not on release line. It targets typesafe-sdk-python 0.6.0 and OpenAPI 0.2.0 for `POST /v1/systemone` and `GET /v1/models`, but versions independently at 0.2.0. Python's `result.nouls["name"]` maps to `response.noul("name")`, mixed types are scanned through the public `answers` map, and retry status selection is a `RetryStatuses` predicate rather than Tenacity.
It needs `serde_json` 1.0.134 or newer as a minimum rather than a pin, and it enables `preserve_order`, which Cargo unifies into your build and can change key ordering. It also moves you to `reqwest` 0.12 and `http` 1, which is what the 0.1 to 0.2 upgrade was. Rust 1.85 or later and edition 2024 are required, and a `blocking` feature exists for non-async scripts.
Yes, anything implementing `POST /v1/systemone` and `GET /v1/models`. Give the base URL as an origin or path prefix without those suffixes, since the client appends them, and keep `?` or `#` out of it because the join is string concatenation. A trailing `/v1` produces `/v1/v1/systemone`, and `tests/contract.rs` sets a mock at `{mock}/gateway/` expecting `/gateway/v1/systemone`.
A 200 body that does not match the schema becomes `ApiErrorKind::ResponseValidation` and names the field path, while HTTP failures surface as `Error::Api` with kinds such as `BadRequest`, `Authentication` or `RateLimited`. By default it retries twice after the first attempt on 408, 429 and 5xx, backing off from 0.5s to 5s with jitter inside a 30s budget, and it honors `Retry-After` and `retry-after-ms`.
Rust 1.85 or later, edition 2024, with typesafe-sdk 0.2, tokio and serde_json. The builder is typestated so build() exists only after api_key, a missing key is a compile error, and constructor values win over TYPESAFE_API_KEY, TYPESAFE_BASE_URL, TYPESAFE_DEFAULT_MODEL and TYPESAFE_LOG_LEVEL.
The default model is jev-latest, the timeout is 10 seconds per attempt, and retries are two after the first on 408, 429 and 5xx with jitter inside a 30-second budget. Per-call overrides go on SystemOneOpts (model, timeout, retry, extra_headers, extra_body) or ModelsOpts, with extra_body a shallow last-write-wins merge.
A wire module with the same types the client sends and decodes. Deserialize a request into SystemOneRequest, build replies with SystemOneResponse::new plus answer constructors, and mount handlers at wire::SYSTEM_ONE_PATH and wire::MODELS_PATH. Unknown question types stay Question::Raw and unknown top-level keys stay in extra, so a gateway can forward without dropping anything.

An async Rust client for models served through the System One API: typed Noul, Choice and Score questions go out with one state and typed answers come back, over a single multiplexed HTTP/2 connection with no vendor built in.

An unofficial async Rust client for the TypeSafe System One API in which each question hands back a key typed by its answer, so reading a choice answer as a probability fails to compile.

Original write-ups on what this entry is for.
Closed weights have not stopped the ecosystem from rebuilding the shape in the open. API-compatible servers, retrained heads on small models, and inference-time tricks that skip generation entirely.
