Enum SessionMode 

pub enum SessionMode {
    PerCommand,
    Stateful,
}

Session mode for hybrid routing

In hybrid mode, sessions can dynamically transition between per-command and stateful modes. This allows load balancing for stateless commands while supporting stateful commands by switching to dedicated connections.

Variants

PerCommand

Per-command routing mode - each command can use a different backend

Benefits:

• Load balancing across multiple backend servers
• Better resource utilization
• Fault tolerance (can route around failed backends)

Limitations:

• Cannot support stateful commands (MODE READER, GROUP, etc.)
• Slightly higher latency (connection pool overhead)

Stateful

Stateful mode - using a dedicated backend connection

Benefits:

• Lowest latency (no pool overhead)
• Supports stateful commands
• Simple 1:1 client-to-backend mapping

Limitations:

• No load balancing (one backend per client)
• Less efficient resource usage

Trait Implementations

impl Clone for SessionMode

fn clone(&self) -> SessionMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionMode

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

Formats the value using the given formatter.

impl PartialEq for SessionMode

fn eq(&self, other: &SessionMode) -> 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.
