Struct JsonRpcExtractor

pub struct JsonRpcExtractor {
    pub parsed: Value,
    pub method: String,
    pub id: Id,
}

Parses a JSON-RPC request, and returns the request ID, the method name, and the parameters. If the request is invalid, returns an error.

use axum_jrpc::{JrpcResult, JsonRpcExtractor, JsonRpcResponse};

fn router(req: JsonRpcExtractor) -> JrpcResult {
  let req_id = req.get_answer_id();
  let method = req.method();
  match method {
    "add" => {
       let params: [i32;2] = req.parse_params()?;
       return Ok(JsonRpcResponse::success(req_id, params[0] + params[1]));
    }
    m =>  Ok(req.method_not_found(m))
  }
}

Trait Implementations

impl Clone for JsonRpcExtractor

fn clone(&self) -> JsonRpcExtractor

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsonRpcExtractor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S> FromRequest<S> for JsonRpcExtractor

where Bytes: FromRequest<S>, S: Send + Sync,

type Rejection = JsonRpcResponse

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request(req: Request, state: &S) -> Result<Self, Self::Rejection>

Perform the extraction.
