# Rust API for fatcat

Fatcat is a scalable, versioned, API-oriented catalog of bibliographic entities and file metadata.  <!-- STARTLONGDESCRIPTION --> These API reference documents, along with client software libraries, are generated automatically from an OpenAPI 2.0 (\"Swagger\") definition file.  ## Introduction   A higher-level introduction to the API, as well as a description of the fatcat data model, are available in [\"The Fatcat Guide\"](https://guide.fatcat.wiki/). The guide also includes a [Cookbook](https://guide.fatcat.wiki/cookbook.html) section demonstrating end-to-end tasks like creating entities as part of editgroups, or safely merging duplicate entities.  ### Expectations and Best Practices  A test/staging QA API instance of fatcat is available at <https://api.qa.fatcat.wiki/v0>. The database backing this instance is separate from the production interface, and is periodically rebuilt from snapshots of the full production database, meaning that edits on the QA server will *NOT* persist, and that semantics like the changelog index monotonically increasing *MAY* be broken. Developers are expexcted to test their scripts and tools against the QA instance before running against production.  NOTE: as of Spring 2021, the QA server is temporarily unavailable.  Fatcat is made available as a gratis (no cost) and libre (freedom preserving) service to the public, with limited funding and resources. We welcome new and unforseen uses and contributions, but may need to impose restrictions (like rate-limits) to keep the service functional for other users, and in extreme cases reserve the option to block accounts and IP ranges if necessary to keep the service operational.  The Internet Archive owns and operates it's own server equipment and data centers, and operations are optimized for low-cost, not high-availability. Users and partners should expect some downtime on the fatcat API, on the order of hours a month.  Periodic metadata exports are available for batch processing, and database snapshots can be used to create locally-hosted mirrors of the service for more intensive and reliable querying.  ### Other Nitty Gritties  Cross-origin requests are allowed for the API service, to enable third parties to build in-browser applications.  A metadata search service is available at <https://search.fatcat.wiki>. The API is currently the raw elasticsearch API, with only GET (read) requests allowed. This public service is experimental and may be removed or limited in the future.  ## Authentication  The API allows basic read-only \"GET\" HTTP requests with no authentication. Proposing changes to the metadata, or other mutating requests (\"PUT\", \"POST\", \"DELETE\") all require authentication, and some operations require additional account permissions.  End-user account creation and login happens through the web interface. From a logged-in editor profile page, you can generate a API token. Tokens are \"macaroons\", similar to JWT tokens, and are used for all API authentication. The web interface includes macaroons in browser cookies and passes them through to the API to authenticate editor actions.  <!-- ReDoc-Inject: <security-definitions> --> <!-- ENDLONGDESCRIPTION --> 

## Overview
This client/server was generated by the [swagger-codegen]
(https://github.com/swagger-api/swagger-codegen) project.
By using the [OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote server, you can easily generate a server stub.

This autogenerated project defines an API crate `fatcat` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* A `Client` type which implements `Api` and issues HTTP requests for each operation.
* A router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.

It also contains an example server and client which make use of `fatcat`:
* The example server starts up a web server using the `fatcat` router,
  and supplies a trivial implementation of `Api` which returns failure for every operation.
* The example client provides a CLI which lets you invoke any single operation on the
  `fatcat` client by passing appropriate arguments on the command line.

You can use the example server and client as a basis for your own code.
See below for [more detail on implementing a server](#writing-a-server).

### HTTPS
The examples can be run in HTTPS mode by passing in the flag `--https`, for example:

```
cargo run --example server -- --https
```

This will use the keys/certificates from the examples directory. Note that the server chain is signed with
`CN=localhost`.


## Writing a server

The server example is designed to form the basis for implementing your own server. Simply follow these steps.

* Set up a new Rust project, e.g., with `cargo init --bin`.
* Insert `fatcat` into the `members` array under [workspace] in the root `Cargo.toml`, e.g., `members = [ "fatcat" ]`.
* Add `fatcat = {version = "0.4.0", path = "fatcat"}` under `[dependencies]` in the root `Cargo.toml`.
* Copy the `[dependencies]` and `[dev-dependencies]` from `fatcat/Cargo.toml` into the root `Cargo.toml`'s `[dependencies]` section.
  * Copy all of the `[dev-dependencies]`, but only the `[dependencies]` that are required by the example server. These should be clearly indicated by comments.
  * Remove `"optional = true"` from each of these lines if present.

Each autogenerated API will contain an implementation stub and main entry point, which should be copied into your project the first time:
```
cp fatcat/examples/server.rs src/main.rs
cp fatcat/examples/server_lib/mod.rs src/lib.rs
cp fatcat/examples/server_lib/server.rs src/server.rs
```

Now

* From `src/main.rs`, remove the `mod server_lib;` line, and uncomment and fill in the `extern crate` line with the name of this server crate.
* Move the block of imports "required by the service library" from `src/main.rs` to `src/lib.rs` and uncomment.
* Change the `let server = server::Server {};` line to `let server = SERVICE_NAME::server().unwrap();` where `SERVICE_NAME` is the name of the server crate.
* Run `cargo build` to check it builds.
* Run `cargo fmt` to reformat the code.
* Commit the result before making any further changes (lest format changes get confused with your own updates).

Now replace the implementations in `src/server.rs` with your own code as required.

## Updating your server to track API changes

Later, if the API changes, you can copy new sections  from the autogenerated API stub into your implementation.
Alternatively, implement the now-missing methods based on the compiler's error messages.
