Constant merlin::constants::MERLIN_PROTOCOL_LABEL

pub const MERLIN_PROTOCOL_LABEL: &[u8]

Domain separation label to initialize the STROBE context.

This is not to be confused with the crate's semver string: the latter applies to the API, while this label defines the protocol. E.g. it is possible that crate 2.0 will have an incompatible API, but implement the same 1.0 protocol.
