Attribute Macro implement 

#[implement]

Implement a given API trait on this client.

The client needs to have at least two fields:

• the “inner” client that is used to dispatch the request
• the “base_url” of the server the request should be sent to

If these fields are literally named inner and base_url, then they will be automatically detected by this macro. If you wish to use alternative names, you can use the attributes #[jsonrpc_client(inner)] and #[jsonrpc_client(base_url)] to mark them accordingly.

Example

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