# ruma-api-macros
|
|
|
|
**ruma-api-macros** provides a procedural macro for easily generating [ruma-api](https://github.com/ruma/ruma-api)-compatible API endpoints.
|
|
You define the endpoint's metadata, request fields, and response fields, and the macro generates all the necessary types and implements all the necessary traits.
|
|
|
|
## Usage
|
|
|
|
This crate is not meant to be used directly; instead, you can use it through the re-exports in ruma-api.
|
|
|
|
Here is an example that shows most of the macro's functionality:
|
|
|
|
```rust
|
|
pub mod some_endpoint {
|
|
use ruma_api::ruma_api;
|
|
|
|
ruma_api! {
|
|
metadata: {
|
|
description: "Does something.",
|
|
method: GET, // An `http::Method` constant. No imports required.
|
|
name: "some_endpoint",
|
|
path: "/_matrix/some/endpoint/:baz", // Variable path components start with a colon.
|
|
rate_limited: false,
|
|
authentication: None,
|
|
}
|
|
|
|
request: {
|
|
// With no attribute on the field, it will be put into the body of the request.
|
|
pub foo: String,
|
|
|
|
// This value will be put into the "Content-Type" HTTP header.
|
|
#[ruma_api(header = CONTENT_TYPE)]
|
|
pub content_type: String
|
|
|
|
// This value will be put into the query string of the request's URL.
|
|
#[ruma_api(query)]
|
|
pub bar: String,
|
|
|
|
// This value will be inserted into the request's URL in place of the
|
|
// ":baz" path component.
|
|
#[ruma_api(path)]
|
|
pub baz: String,
|
|
}
|
|
|
|
response: {
|
|
// This value will be extracted from the "Content-Type" HTTP header.
|
|
#[ruma_api(header = CONTENT_TYPE)]
|
|
pub content_type: String
|
|
|
|
// With no attribute on the field, it will be extracted from the body of the response.
|
|
pub value: String,
|
|
}
|
|
|
|
// An error can also be specified or defaults to `ruma_api::error::Void`.
|
|
error: ruma_api::Error
|
|
}
|
|
}
|
|
```
