Struct RestartPolicy 

pub struct RestartPolicy {
    pub initial_delay_ms: u64,
    pub max_delay_ms: u64,
    pub backoff_multiplier: f64,
    pub max_restart_attempts: u32,
}

Available on crate features mcp and tools only.

Controls auto-restart behavior with exponential backoff.

When a managed server crashes, the manager uses this policy to determine how long to wait before restarting and when to give up.

Backoff Formula

delay(attempt) = min(initial_delay_ms × backoff_multiplier ^ attempt, max_delay_ms)

Example

use adk_tool::mcp::manager::RestartPolicy;

let json = r#"{
    "initialDelayMs": 500,
    "maxDelayMs": 15000,
    "backoffMultiplier": 2.0,
    "maxRestartAttempts": 5
}"#;

let policy: RestartPolicy = serde_json::from_str(json).unwrap();
assert_eq!(policy.initial_delay_ms, 500);
assert_eq!(policy.max_restart_attempts, 5);

Fields

initial_delay_ms: u64

Initial delay in milliseconds before the first restart attempt. Default: 1000.

max_delay_ms: u64

Maximum delay in milliseconds between restart attempts. Default: 30000.

backoff_multiplier: f64

Multiplier applied to the delay after each failed attempt. Default: 2.0.

max_restart_attempts: u32

Maximum number of consecutive restart attempts before giving up. Default: 10.
