0.5.2 - 2025-06-23

Changed

• Moved the futures dependency to dev-dependencies
• MSRV is now 1.48. Since we don't have a stated MSRV policy and 1.48 is almost older than this crate, much less version 0.5.0, I am fine with doing this in a patch release.

Changed

• Move to pin-project-lite instead of pin-project (#21)
• RetryFuture::on_retry has additional type parameter and trait bound (#22)

Fixed

• Fixed inference issues with RetryFuture::on_retry (#22)

Release version 0.4.0 (#19)

Added

• BackoffStrategy is now implemented directly for functions of the right type.
• Explicit constructs have been added to each back-off strategy. This makes it possible to define a new strategy that wraps one of the types provided by tryhard.

Changed

• BackoffStrategy is now generic over the lifetime of the error given to BackoffStrategy::delay.
• The output of the future returned by OnRetry::on_retry has been fixed to (). As the future is given to tokio::spawn requiring () is nicer.

Deprecated

• N/A

Removed

• CustomBackoffStrategy has been removed since BackoffStrategy is now implemented directly on functions of the right type.
• Tokio 0.2 support has been removed. Tokio 1 is now the only version supported.

Fixed

• RetryFuture no longer requires the error type to implement Display.

Security

• N/A

Added

• Support for Tokio 1.0 added. Tokio 1.0 support is on by default or by enabling the tokio-1 feature.
• Add RetryFutureConfig which let you retry several futures in the same way.
• All backoff strategy types now implement Copy and Clone.

Removed

• Support for Tokio 0.3 has been removed. 0.2 is still supported.

Fixed

• CustomBackoffStrategy now implements Debug regardless of its type parameter.

Changed

• Changed from using Tokio 0.2 by default to using Tokio 0.3. You can switch back to Tokio 0.2 by declaring your dependency with tryhard = { version = "your-version", default-features = false, features = ["tokio-02"] }.

Generalize performing stuff before retries

Added

• First release!
