jsonrpc_client

Attribute Macro api

Source 
#[api]
Expand description

Define the API of the JSON-RPC server you want to talk to.

All methods of this trait must be async. Additionally, the trait cannot have other items such as const or type declarations. You can define the JSON-RPC version through the version attribute. For now, all this does is sent the correct version property in the JSON-RPC request.

ยงExample

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