Trait Implementations§

Source§

impl<F> Command<F> for SetCommand<ConfirmationResponse>
where F: From<CommandBuilder> + ToStringOption,

Source§

type Response = ()

Response type, either a custom evaluated “high-level” response or the original RESP frame
Source§

fn encode(&self) -> F

Encodes the command to RESP2/RESP3 frame
Source§

fn eval_response(&self, frame: F) -> Result<Self::Response, ResponseTypeError>

The command has the ability to evaluate the response frame and craft its own high level response from that. Its also possible to just return 1:1 the RESP2 frame. Read more
