Enum Proto 

pub enum Proto {
    Resp2,
    Resp3,
}

RESP2 or RESP3, per connection.

A connection starts at RESP2 and moves to RESP3 when the client sends HELLO 3. It can move back. The version is a property of the connection and never of the command, which is why every reply writer takes it once at construction rather than at each call.

Variants

Resp2

The protocol every client understands. Five types and nothing else.

Resp3

Redis 6 and later. Maps, sets, doubles, booleans, push messages, and a null that is not a length of minus one.

Implementations

impl Proto

pub const fn version(self) -> i64

The number a HELLO reply reports, and the number HELLO takes.

pub const fn from_version(v: i64) -> Option<Proto>

The protocol for a HELLO argument, or None if there is no such version. HELLO 4 is an error and this is where that is decided.

pub const fn is_resp3(self) -> bool

Whether the richer type set is available.
