Enum RespVersion 

pub enum RespVersion {
    V2,
    V3,
}

Which version of RESP a connection is speaking. Negotiated via the HELLO command — RESP2 is the default for backwards compatibility with every Redis 6.x and earlier client; RESP3 is opt-in via HELLO 3 and unlocks the additive reply types (Reply::Map / Reply::Set / Reply::Double / Reply::Boolean / Reply::Verbatim / Reply::BigNumber / Reply::Null / Reply::Push / Reply::BlobError) plus out-of-band push frames for PUBLISH delivery.

Stored per-connection in kevy-rt and forwarded to dispatch so each reply encoder can pick the right wire shape — see the kevy v2 RESP3 design notes for the full phase plan.

Variants

V2

RESP2 — every reply is one of the seven legacy prefixes (+ - : $ * $-1 *-1). Default for backward compatibility.

V3

RESP3 — adds 9 reply prefixes (% ~ , # = ( _ > !) plus attributes (|). Opt-in via HELLO 3.

Trait Implementations

impl Clone for RespVersion

fn clone(&self) -> RespVersion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for RespVersion

impl Debug for RespVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RespVersion

fn default() -> RespVersion

Returns the “default value” for a type.

impl Eq for RespVersion

impl PartialEq for RespVersion

fn eq(&self, other: &RespVersion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
