v0.8.0-beta.1

Fixes

• Fix compatibility issue between IntoSubsystem and custom error types

v0.8.0-beta.0

Breaking Changes

• Error type is now configurable via generic
  • Enables custom error types for projects that are then recoverable from GracefulShutdownError in their original type
  • For more infos, see example 18_error_type_passthrough

v0.7.0

Breaking Changes

• Rewrite Errors
  • Errors can now be prettified with miette
  • Errors now carry the error sources including the actual errors from the failed subsystems
• Display a warning if the Toplevel object isn't consumed (via handle_shutdown_requests)
• Cancel all subsystems connected to the Toplevel object when the Toplevel object is dropped

Non-breaking changes

• Change recommended error wrapper library from anyhow to miette.
  • Compatibility to other error handling wrapper libraries stays unchanged.
• Add IntoSubsystem trait to make writing struct-based subsystems more convenient

v0.6.0

Breaking Changes

• Subsystems can return Err<Into<Box<dyn Error + Send + Sync>>> instead of Err<Into<anyhow::Error>>
  • Allows all error types that can be converted to Box<dyn Error + Send + Sync>
  • Should be compatible with existing code, but increases compatibility with new error handling crates
• Toplevel::handle_shutdown_requests can now return all types that implement From<GracefulShutdownError>, which should integrate seamlessly with most return types from main(), like anyhow::Result, Box<dyn Error> or eyre::Result

v0.6.0-beta.0

Breaking Changes

• Subsystems can return Err<Into<Box<dyn Error + Send + Sync>>> instead of Err<Into<anyhow::Error>>
  • Allows all error types that can be converted to Box<dyn Error + Send + Sync>
  • Should be compatible with existing code, but increases compatibility with new error handling crates
• Toplevel::handle_shutdown_requests can now return all types that implement From<GracefulShutdownError>, which should integrate seamlessly with most return types from main(), like anyhow::Result, Box<dyn Error> or eyre::Result

v0.5.0

Breaking Changes

• Subsystems can return Err<Into<anyhow::Error>> instead of Err<anyhow::Error>
  • No longer imposes the anyhow dependency on library users
  • Should not be a problem in most cases, but closures only returning Ok(()) will now fail to compile, as Rust is unable to deduce the Error type

v0.4.4

Changes

• Make SubsystemHandle::start() a non-mut function (@Trivernis)
  • This removes the necessity of the handle argument to be mut, making it much easiert to pass it around, to store it in structs and to use it as a shared reference.

v0.4.3

Changes

• Fix: Errors during partial shutdown no longer cause global shutdown.
  • Instead, errors get properly delivered to the task that issued the partial shutdown.

v0.4.2

Changes

• Reduce Rust version to 2018
  • Adds compatibility with Rust 2018 projects

v0.4.1

Breaking Changes

• Rename Toplevel::wait_for_shutdown to Toplevel::handle_shutdown_requests to make it clearer what the purpose of this function is
• Implement partial shutdown API
  • Change return value of SubsystemHandle::create() to NestedSubsystem
  • Add SubsystemHandle::perform_partial_shutdown(NestedSubsystem)
  • Add NestedSubsystem struct and PartialShutdownError enum
