Struct RetryBudget 

pub struct RetryBudget {
    pub max_retries: u32,
    pub delay: Duration,
}

Core traits and types.

Always available regardless of feature flags. Includes:

• Agent - The fundamental trait for all agents
• Tool / Toolset - For extending agents with capabilities
• Session / State - For managing conversation context
• Event - For streaming agent responses
• AdkError / Result - Unified error handling Configuration for automatic tool retry on failure.

Controls how many times a failed tool execution is retried before propagating the error. Applied as a flat delay between attempts (no exponential backoff in V1).

Example

use std::time::Duration;
use adk_core::RetryBudget;

// Retry up to 2 times with 500ms between attempts (3 total attempts)
let budget = RetryBudget::new(2, Duration::from_millis(500));
assert_eq!(budget.max_retries, 2);

Fields

max_retries: u32

Maximum number of retry attempts (not counting the initial attempt). E.g., max_retries: 2 means up to 3 total attempts.

delay: Duration

Delay between retries. Applied as a flat delay (no backoff in V1).

Implementations

impl RetryBudget

pub fn new(max_retries: u32, delay: Duration) -> RetryBudget

Create a new retry budget.

Arguments

• max_retries - Maximum retry attempts (not counting the initial attempt)
• delay - Flat delay between retry attempts
