Struct DiscoverExchange 

#[non_exhaustive]
pub struct DiscoverExchange<'a> {
    pub request: Option<(u64, Option<&'a Value>)>,
    pub result: Option<(u64, &'a Value)>,
    pub error: Option<u64>,
}

The observed server/discover exchange — the optional stateless capability/identity probe — when present. A session is valid with no discovery at all.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

request: Option<(u64, Option<&'a Value>)>

The server/discover request: its event seq and params value (if any).

result: Option<(u64, &'a Value)>

The successful server/discover result: its event seq and result value.

error: Option<u64>

The seq of an error response to the server/discover request.
