Retrying requests

The Provider can be configured to retry a request upon receiving a io::Error.

Note: Currently all node errors are received as io::Errors. So, if configured, a retry will happen even if, for example, a transaction failed to verify.

We can configure the number of retry attempts and the retry strategy as detailed below.

RetryConfig

The retry behavior can be altered by giving a custom RetryConfig. It allows for configuring the maximum number of attempts and the interval strategy used.

{{#include ../../../examples/providers/src/lib.rs:configure_retry}}

Interval strategy - Backoff

Backoff defines different strategies for managing intervals between retry attempts. Each strategy allows you to customize the waiting time before a new attempt based on the number of attempts made.

Variants

• Linear(Duration): Default Increases the waiting time linearly with each attempt.
• Exponential(Duration): Doubles the waiting time with each attempt.
• Fixed(Duration): Uses a constant waiting time between attempts.
