Function decode_server_value_body 

pub fn decode_server_value_body(
    discriminant: ServerDiscriminant,
    version: ProtocolVersion,
    body: &[u8],
) -> Result<(ServerValue, ProtocolVersion), CodecError>

Decodes one exact semantic server-value body under v1.0.

The concrete protocol version is returned beside the decoded value so a complete-frame caller can preserve its already-validated prefix value.

Errors

Returns the canonical structural decode class, or CodecError::UnsupportedVersion when version is not v1.0.
