[dependabot]

Bumps tokio-graceful-shutdown from 0.17.1 to 0.19.3.

Release notes

Sourced from tokio-graceful-shutdown's releases.

v0.19.3

Changes

• Fix missing semicolon in usage example (#136)

v0.19.2

Changes

• Convert over-ambitious panics to warnings in: (#132)
  • Toplevel::catch_signals
  • Subsystem panic handler
• Improve documentation of SubsystemHandle::wait_for_children (#132)

v0.19.1

Changes

• Cleanup dev-dependencies:
  • Bump console-subscriber to 0.5.0
  • Remove obsolete dependencies:
    • futures-util
    • tower
    • gcc

v0.19.0

Breaking Changes

• Subsystems now take the SubsystemHandle parameter as a mutable reference (&mut SubsystemHandle) (#125).
  • It was always meant to be like that, but technical limitations in older Rust versions prevented the combination of mutable references in generic async functions.
  • This change has some side effects, so I created a small migration guide.

v0.18.0

Breaking Changes

• Remove async_trait dependency now that RPITIT was stabilized (#124)
  • Rework trait IntoSubsystem to use RPITIT instead of async_trait.
