Rust API for fatcat

Fatcat is a scalable, versioned, API-oriented catalog of bibliographic entities and file metadata. 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". The guide also includes a Cookbook 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. 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 bulid in-browser applications. A metadata search service is available at https://search.fatcat.wiki (and https://search.qa.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.

Overview

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

README

• API version: 0.3.1
• Build date: 2019-09-19T00:21:33.977Z For more information, please visit https://fatcat.wiki

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.

Examples

Run examples with:

cargo run --example <example-name>

To pass in arguments to the examples, put them after --, for example:

cargo run --example client -- --help

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 = "0.3.1", 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.
