Fields

max_retries: u32

base_wait_ms: u64

max_wait_ms: u64

backoff_factor: f64

retryable_http_codes: HashSet<u16>

max_retries_per_server: u32

Implementations

impl RetryPolicy

pub fn new(max_retries: u32, base_wait_ms: u64) -> Self

pub fn with_max_retries(self, max_retries: u32) -> Self

pub fn with_max_per_server(self, n: u32) -> Self

pub fn with_max_wait_ms(self, ms: u64) -> Self

pub fn max_tries(&self) -> u32

Alias for max_retries for compatibility with the engine retry loop.

pub fn compute_wait(&self, attempt: u32) -> Option<Duration>

pub fn wait_duration(&self, attempt: u32) -> Duration

Compute wait duration using exponential backoff (Duration-based API).

This is equivalent to compute_wait but returns a Duration directly, clamped between base_wait and max_wait.

pub fn should_retry(&self, attempt: u32, error: &Aria2Error) -> bool

Check whether a retry should be attempted based on the error type.

Returns true if the attempt count has not been exhausted and the error is a recoverable Aria2Error.

pub fn should_retry_http(&self, status_code: u16) -> bool

pub fn should_retry_error(&self, error_str: &str) -> bool

pub fn is_exhausted(&self, attempts: u32) -> bool

pub fn total_estimated_wait_sec(&self) -> f64

pub fn stats(&self) -> RetryPolicyStats
