Struct coap_lite::error::HandlingError

pub struct HandlingError {
    pub code: Option<ResponseType>,
    pub message: String,
}

Participatory mechanism for the low-level library to communicate to callers that unexpected errors occurred while handling standard parts of the protocol that should ideally deliver a failure message to the peer. But rather than apply that response message ourselves we yield this error and ask the caller to perform the conversion. For convenience, this can be done with crate::CoapRequest::apply_from_error.

Fields

code: Option<ResponseType>

message: String
