Trait jsonrpc_client::SendRequest

pub trait SendRequest: 'static where
    Error<Self::Error>: From<Self::Error>, {
    type Error: StdError;
    fn send_request<'life0, 'async_trait, P>(
        &'life0 self, 
        endpoint: Url, 
        body: String
    ) -> Pin<Box<dyn Future<Output = Result<Response<P>, Self::Error>> + Send + 'async_trait>>
    where
        P: DeserializeOwned,
        P: 'async_trait,
        'life0: 'async_trait,
        Self: 'async_trait;
}

A trait abstracting over how a request is actually sent to a server.

This trait needs to be implemented on the “inner” client.

Example

struct MyHttpClient;

struct MyError;


#[async_trait::async_trait]
impl SendRequest for MyHttpClient {
    type Error = MyError;

    async fn send_request<P>(&self, endpoint: Url, body: String) -> Result<Response<P>, Self::Error>
    where
        P: DeserializeOwned,
    {
        // send the given body to the given endpoint and deserialize the response as `Response<P>`
    }
}

#[jsonrpc_client::api]
pub trait Math {
    async fn subtract(&self, subtrahend: i64, minuend: i64) -> i64;
}

#[jsonrpc_client::implement(Math)]
struct Client {
    inner: MyHttpClient,
    base_url: Url,
}
