Struct MailOutboxRetryPolicy 

pub struct MailOutboxRetryPolicy {
    pub max_attempts: i32,
    pub max_error_len: usize,
}

Retry and truncation policy for an outbox dispatcher.

Fields

max_attempts: i32

Maximum number of delivery attempts before permanent failure.

max_error_len: usize

Maximum stored error string length, counted in Unicode scalar values.

Implementations

impl MailOutboxRetryPolicy

pub const fn new(max_attempts: i32, max_error_len: usize) -> Self

Creates a retry policy.

pub const fn should_permanently_fail(&self, attempt_count: i32) -> bool

Returns whether attempt_count should permanently fail.

pub const fn retry_delay_secs(&self, attempt_count: i32) -> i64

Returns the delay before the next delivery retry.

pub fn truncate_error(&self, error: &str) -> String

Truncates a delivery error according to this policy.

pub fn delivery_failure_decision( &self, attempt_count: i32, error: impl AsRef<str>, ) -> MailOutboxDeliveryFailureDecision

Classifies a failed delivery attempt.

attempt_count should be the post-delivery attempt count that the product crate will persist on the outbox row.

Trait Implementations

impl Clone for MailOutboxRetryPolicy

fn clone(&self) -> MailOutboxRetryPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MailOutboxRetryPolicy

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

Formats the value using the given formatter.

impl PartialEq for MailOutboxRetryPolicy

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