Retry config.

These settings determine when a failed task attempt is retried.

Fields

max_attempts: i32

Number of attempts per task.

Cloud Tasks will attempt the task max_attempts times (that is, if the first attempt fails, then there will be max_attempts - 1 retries). Must be >= -1.

If unspecified when the queue is created, Cloud Tasks will pick the default.

-1 indicates unlimited attempts.

This field has the same meaning as task_retry_limit in queue.yaml/xml.

max_retry_duration: Option<Duration>

If positive, max_retry_duration specifies the time limit for retrying a failed task, measured from when the task was first attempted. Once max_retry_duration time has passed and the task has been attempted [max_attempts][google.cloud.tasks.v2.RetryConfig.max_attempts] times, no further attempts will be made and the task will be deleted.

If zero, then the task age is unlimited.

If unspecified when the queue is created, Cloud Tasks will pick the default.

max_retry_duration will be truncated to the nearest second.

This field has the same meaning as task_age_limit in queue.yaml/xml.

min_backoff: Option<Duration>

A task will be [scheduled][google.cloud.tasks.v2.Task.schedule_time] for retry between [min_backoff][google.cloud.tasks.v2.RetryConfig.min_backoff] and [max_backoff][google.cloud.tasks.v2.RetryConfig.max_backoff] duration after it fails, if the queue’s [RetryConfig][google.cloud.tasks.v2.RetryConfig] specifies that the task should be retried.

If unspecified when the queue is created, Cloud Tasks will pick the default.

min_backoff will be truncated to the nearest second.

This field has the same meaning as min_backoff_seconds in queue.yaml/xml.

max_backoff: Option<Duration>

A task will be [scheduled][google.cloud.tasks.v2.Task.schedule_time] for retry between [min_backoff][google.cloud.tasks.v2.RetryConfig.min_backoff] and [max_backoff][google.cloud.tasks.v2.RetryConfig.max_backoff] duration after it fails, if the queue’s [RetryConfig][google.cloud.tasks.v2.RetryConfig] specifies that the task should be retried.

If unspecified when the queue is created, Cloud Tasks will pick the default.

max_backoff will be truncated to the nearest second.

This field has the same meaning as max_backoff_seconds in queue.yaml/xml.

max_doublings: i32

The time between retries will double max_doublings times.

A task’s retry interval starts at [min_backoff][google.cloud.tasks.v2.RetryConfig.min_backoff], then doubles max_doublings times, then increases linearly, and finally retries at intervals of [max_backoff][google.cloud.tasks.v2.RetryConfig.max_backoff] up to [max_attempts][google.cloud.tasks.v2.RetryConfig.max_attempts] times.

For example, if [min_backoff][google.cloud.tasks.v2.RetryConfig.min_backoff] is 10s, [max_backoff][google.cloud.tasks.v2.RetryConfig.max_backoff] is 300s, and max_doublings is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of [max_backoff][google.cloud.tasks.v2.RetryConfig.max_backoff] until the task has been attempted [max_attempts][google.cloud.tasks.v2.RetryConfig.max_attempts] times. Thus, the requests will retry at 10s, 20s, 40s, 80s, 160s, 240s, 300s, 300s, ….

If unspecified when the queue is created, Cloud Tasks will pick the default.

This field has the same meaning as max_doublings in queue.yaml/xml.

Trait Implementations

impl Clone for RetryConfig

fn clone(&self) -> RetryConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RetryConfig

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

Formats the value using the given formatter.

impl Default for RetryConfig

fn default() -> Self

Returns the “default value” for a type.

impl Message for RetryConfig

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

impl PartialEq for RetryConfig

fn eq(&self, other: &RetryConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
