Enum RetryPredicate 

pub enum RetryPredicate {
    Default,
    Replace(fn(&OdosError) -> bool),
    DefaultExcept(fn(&OdosError) -> bool),
}

How a caller-supplied predicate composes with the SDK’s default retry decision tree.

The default decision tree is OdosError::is_retryable gated by RetryConfig::retry_server_errors. Each variant chooses how a custom predicate interacts with that tree:

• RetryPredicate::Default uses only the built-in tree.
• RetryPredicate::Replace replaces the tree entirely; the predicate is the sole authority on whether to retry.
• RetryPredicate::DefaultExcept runs the built-in tree but vetoes retries when the predicate returns true. Useful for blacklisting specific error shapes without reimplementing the default policy.

max_retries and the rate-limit / 429 hard-gate apply to every variant.

Variants

Default

Use the SDK’s built-in decision tree.

Replace(fn(&OdosError) -> bool)

Replace the default decision tree entirely. The predicate is the sole authority on whether to retry. The RetryConfig::retry_server_errors flag is bypassed under this variant.

DefaultExcept(fn(&OdosError) -> bool)

Run the default decision tree, but veto retries when the predicate returns true. Equivalent to !veto(err) && default_should_retry(err).
