Attribute Macro ruma_common::api::request
source · #[request]
api
only.Expand description
Generates OutgoingRequest
and IncomingRequest
implementations.
The OutgoingRequest
impl is on the Request
type this attribute is used on. It is
feature-gated behind cfg(feature = "client")
.
The IncomingRequest
impl is on IncomingRequest
, which is either a type alias to
Request
or a fully-owned version of the same, depending of whether Request
has any
lifetime parameters. It is feature-gated behind cfg(feature = "server")
.
The generated code expects a METADATA
constant of type Metadata
to be in scope,
alongside a Response
type that implements OutgoingResponse
(for
cfg(feature = "server")
) and / or IncomingResponse
(for cfg(feature = "client")
).
§Attributes
To declare which part of the request a field belongs to:
#[ruma_api(header = HEADER_NAME)]
: Fields with this attribute will be treated as HTTP headers on the request. The value must implementToString
andFromStr
. Generally this is aString
. The attribute value shown above asHEADER_NAME
must be aconst
expression of the typehttp::header::HeaderName
, like one of the constants fromhttp::header
, e.g.CONTENT_TYPE
. During deserialization of the request, if the field is anOption
and parsing the header fails, the error will be ignored and the value will beNone
.#[ruma_api(path)]
: Fields with this attribute will be inserted into the matching path component of the request URL. If there are multiple of these fields, the order in which they are declared must match the order in which they occur in the request path.#[ruma_api(query)]
: Fields with this attribute will be inserting into the URL’s query string.#[ruma_api(query_all)]
: Instead of individual query fields, one query_all field, of any type that can be (de)serialized by serde_html_form, can be used for cases where multiple endpoints should share a query fields type, the query fields are better expressed as anenum
rather than astruct
, or the endpoint supports arbitrary query parameters.- No attribute: Fields without an attribute are part of the body. They can use
#[serde]
attributes to customize (de)serialization. #[ruma_api(body)]
: Use this if multiple endpoints should share a request body type, or the request body is better expressed as anenum
rather than astruct
. The value of the field will be used as the JSON body (rather than being a field in the request body object).#[ruma_api(raw_body)]
: Likebody
in that the field annotated with it represents the entire request body, but this attribute is for endpoints where the body can be anything, not just JSON. The field type must beVec<u8>
.
§Examples
pub mod do_a_thing {
use ruma_common::{api::request, OwnedRoomId};
// const METADATA: Metadata = metadata! { ... };
#[request]
pub struct Request {
#[ruma_api(path)]
pub room_id: OwnedRoomId,
#[ruma_api(query)]
pub bar: String,
#[serde(default)]
pub foo: String,
}
// #[response]
// pub struct Response { ... }
}
pub mod upload_file {
use http::header::CONTENT_TYPE;
use ruma_common::api::request;
// const METADATA: Metadata = metadata! { ... };
#[request]
pub struct Request {
#[ruma_api(path)]
pub file_name: String,
#[ruma_api(header = CONTENT_TYPE)]
pub content_type: String,
#[ruma_api(raw_body)]
pub file: Vec<u8>,
}
// #[response]
// pub struct Response { ... }
}
