pub fn json<T>(val: T) -> ReplyDatawhere
T: Serialize,Expand description
Build a JSON ReplyData from any Serialize value.
Panics on serialization failure. Most domain types (those with derived
Serialize over stringy fields) never fail, but custom impls can.
The reply! macro uses try_json internally to convert that case
into a WebError::Internal (→ 500) rather than a handler-level panic
that would drop the whole connection.
Prefer reply!(my_value) over calling this directly.
