Enum HandlerResult 

#[non_exhaustive]
pub enum HandlerResult {
    Ok(Value),
    Err(JsonRpcError),
}

The two outcomes a request handler can produce.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ok(Value)

Success — value is JSON-serialized into the response’s result.

Err(JsonRpcError)

Failure — error is serialized into the response’s error.
