It's also extremely -handy for handling dependencies and helping to modularise your project better. - -*Note: If you've installed rust through rustup, you should have ``cargo`` -installed.* - -#### Rust Terminology - -When developing rust, you'll come across some terminology that differs to -other programming languages you may have used. - -* **Trait**: A trait is a collection of methods defined for a type, they can be -implemented for any data type. -* **Struct**: A custom data type that lets us name and package together -multiple related values that make a meaninguful group. -* **Crate**: A crate is synonymous with a *library* or *package* in other -languages. They can produce an executable or library depending on the -project. -* **Module**: A collection of items: functions, structs, traits, and even other -modules. Modules allow you to hierarchically split code into logical units -and manage visibility. -* **Attribute**: Metadata applied to some module, crate or item. -* **Macros**: Macros are powerful meta-programming statements that get expanded -into source code that gets compiled with the rest of the code (Unlike `C` -macros that are pre-processed, Rust macros form an Abstract Syntax Tree). - - -Other good appendix resources: - -* [Keywords](https://doc.rust-lang.org/book/appendix-01-keywords.html) -* [Operators/Symbols](https://doc.rust-lang.org/book/appendix-02-operators.html) -* [Traits](https://doc.rust-lang.org/book/appendix-03-derivable-traits.html) - - -### Understanding the Git Workflow - -Lighthouse utilises git as the primary open-source development tool. To help -with your contributions, it is great to understand the processes used to ensure -everything remains in sync and there's as little conflict as possible when -working on similar files. - -Lighthouse uses the **feature branch** workflow, where each issue, or each -feature, is developed on its own branch and then merged in via a pull-request. - -* [Feature Branch Tutorial](https://www.atlassian.com/git/tutorials/comparing-workflows/feature-branch-workflow) - -## Code Conventions/Styleguide and Ethos - -### Ethos - -**Pull Requests** - -Pull requests should be reviewed by **at least** one "*core developer*" -(someone with write-access to the repo). This should ensure bugs are caught and -the code is kept in a consistent state that follows all conventions and style. - -All discussion (whether in PRs or Issues or in the Gitter) should be respectful -and intellectual. Have fun, but always respect the limits of other people. - -**Testing** - -*"A function is not considered complete until tests exist for it."* - -Generally, tests can be self-contained in the same file. Integration tests -should be added into the ``tests/`` directory in the crate's **root**. - -Large line-count tests should be in a separate file. - -### Rust StyleGuide - -Lighthouse adheres to Rust code conventions as outlined in the [**Rust -Styleguide**](https://github.com/rust-dev-tools/fmt-rfcs/blob/master/guide/guide.md). - -Ensure you use [Clippy](https://github.com/rust-lang/rust-clippy) to lint and -check your code. - -| Code Aspect | Guideline Format | -|:--------------------|:-------------------------------| -| Types | ``UpperCamelCase`` | -| Enums/Enum Variants | ``UpperCamelCase`` | -| Struct Fields | ``snake_case`` | -| Function / Method | ``snake_case`` | -| Macro Names | ``snake_case`` | -| Constants | ``SCREAMING_SNAKE_CASE`` | -| Forbidden name | Trailing Underscore: ``name_`` | - -Other general rust docs: - -* [Rust Other Style Advice](https://github.com/rust-dev-tools/fmt-rfcs/blob/master/guide/advice.md) -* [Cargo.toml Conventions](https://github.com/rust-dev-tools/fmt-rfcs/blob/master/guide/cargo.md) - -### TODOs - -All `TODO` statements should be accompanied by a GitHub issue. - -```rust -pub fn my_function(&mut self, _something &[u8]) -> Result { - // TODO: something_here - // https://github.com/sigp/lighthouse/issues/XX -} -``` - -### Comments - -**General Comments** - -* Prefer line (``//``) comments to block comments (``/* ... */``) -* Comments can appear on the line prior to the item or after a trailing space. -```rust -// Comment for this struct -struct Lighthouse {} - -fn make_blockchain() {} // A comment on the same line after a space -``` - -**Doc Comments** - -* The ``///`` is used to generate comments for Docs. -* The comments should come before attributes. - -```rust -/// Stores the core configuration for this Lighthouse instance. -/// This struct is general, other components may implement more -/// specialized config structs. -#[derive(Clone)] -pub struct LighthouseConfig { - pub data_dir: PathBuf, - pub p2p_listen_port: u16, -} -``` diff --git a/docs/rest_oapi.yaml b/docs/rest_oapi.yaml new file mode 100644 index 000000000..dea892c18 --- /dev/null +++ b/docs/rest_oapi.yaml @@ -0,0 +1,1379 @@ +openapi: "3.0.2" +info: + title: "Lighthouse REST API" + description: "" + version: "0.1.0" + license: + name: "Apache 2.0" + url: "https://www.apache.org/licenses/LICENSE-2.0.html" +tags: + - name: Phase0 + description: Endpoints which will be implemented for phase 0 of Ethereum Serenity + - name: Phase1 + description: Endpoints which will be implemented for phase 1 of Ethereum Serenity + - name: Future + description: Potential future endpoints or optional nice-to-haves + +paths: + /node/version: + get: + tags: + - Phase0 + summary: "Get version string of the running beacon node." + description: "Requests that the beacon node identify information about its implementation in a format similar to a [HTTP User-Agent](https://tools.ietf.org/html/rfc7231#section-5.5.3) field." + responses: + 200: + description: Request successful + content: + application/json: + schema: + $ref: '#/components/schemas/version' + 500: + $ref: '#/components/responses/InternalError' + + /node/genesis_time: + get: + tags: + - Phase0 + summary: "Get the genesis_time parameter from beacon node configuration." + description: "Requests the genesis_time parameter from the beacon node, which should be consistent across all beacon nodes that follow the same beacon chain." + responses: + 200: + description: Request successful + content: + application/json: + schema: + $ref: '#/components/schemas/genesis_time' + 500: + $ref: '#/components/responses/InternalError' + + /node/deposit_contract: + get: + tags: + - Phase0 + summary: "Get the address of the Ethereum 1 deposit contract." + description: "Requests the address of the deposit contract on the Ethereum 1 chain, which was used to start the current beacon chain." + responses: + 200: + description: Request successful + content: + application/json: + schema: + $ref: '#/components/schemas/ethereum_address' + 500: + $ref: '#/components/responses/InternalError' + + /node/syncing: + get: + tags: + - Phase0 + summary: "Poll to see if the the beacon node is syncing." + description: "Requests the beacon node to describe if it's currently syncing or not, and if it is, what block it is up to.
