Struct SessionUpdateConfig 

pub struct SessionUpdateConfig(pub RealtimeConfig);

Available on crate feature realtime only.

A delta payload for safely updating an active realtime session.

Wraps RealtimeConfig to prevent struct duplication. Since all fields are Option<T> and skip serialization if None, omitting fields preserves the server’s active state.

⚠️ WARNING: You must construct a fresh configuration containing only the fields to modify. Wrapping your original startup config will resend immutable fields (like model), causing the provider to reject the update.

This is the idiomatic mechanism for dynamic Finite State Machine (FSM) state transitions, allowing seamless “persona shifts” or tool swaps without dropping the audio connection.

Example

use adk_realtime::config::{SessionUpdateConfig, RealtimeConfig};

// Update *only* the instruction mid-session.
let delta = SessionUpdateConfig(
    RealtimeConfig::default().with_instruction("You are now a travel agent.")
);
