Struct ProjectionRetryPolicy 

pub struct ProjectionRetryPolicy { /* private fields */ }

Controls retry behavior after an application requests a retry.

Implementations

impl ProjectionRetryPolicy

pub fn new( max_retries: u32, initial_delay: Duration, multiplier: f64, maximum_delay: Duration, ) -> Result<Self, ProjectionConfigurationError>

Creates a capped exponential retry policy.

max_retries counts retries after the initial application attempt. u32::MAX is rejected with ProjectionConfigurationError::TooManyRetries because the runner must represent that initial attempt as well. multiplier must be finite and at least 1.0; non-finite values and values below 1.0 produce ProjectionConfigurationError::InvalidRetryMultiplier.

The delay before retry number n is initial_delay * multiplier^(n - 1), capped at maximum_delay. A calculation that exceeds the representable finite duration also uses the cap. Zero is accepted for either delay, including a policy with no delay at all.

pub fn max_retries(&self) -> u32

Returns the number of retries after the initial attempt.

pub fn initial_delay(&self) -> Duration

Returns the delay before the first retry.

pub fn multiplier(&self) -> f64

Returns the multiplier used to increase retry delays.

pub fn maximum_delay(&self) -> Duration

Returns the maximum retry delay.
