Enum Declaration 

pub enum Declaration<'a> {
    Handshake {
        version: &'a str,
        capabilities: Option<&'a Value>,
    },
    Stateless {
        meta: MetaView<'a>,
    },
}

What a peer declared about itself, in this crate’s vocabulary.

Variants

Handshake

A handshake request: the version it asked for, and whatever the protocol also puts in one.

Fields

version: &'a str

The requested version, as the peer spelled it. Parsed here rather than by the engine, because a version this protocol cannot parse is a statement about its vocabulary.

capabilities: Option<&'a Value>

The capabilities the peer advertised, if this protocol has any.

Stateless

A message that negotiates for itself: the reserved keys its metadata carried, and nothing else.

Fields

meta: MetaView<'a>

The metadata the request carried.
