pub const PROTOCOL_VERSION_1: u32 = 1;Expand description
Credential process JSON protocol version.
If the protocol needs to make
a breaking change, a new protocol version should be defined (PROTOCOL_VERSION_2).
This library should offer support for both protocols if possible, by signaling
in the CredentialHello message. Cargo will then choose which protocol to use,
or it will error if there are no common protocol versions available.
