nanonext 1.0.0

New Features

• Integrates with the later package to provide the foundation for truly event-driven (non-polling) promises (thanks @jcheng5 for the initial prototype in #28), where side-effects are enacted asynchronously upon aio completion.
  • request() and request_signal() modified internally to support conversion of 'recvAio' to event-driven promises.
  • later dependency ensures asynchronous R code is always run on the main R thread.
  • later is lazily loaded the first time a promise is used, and hence does not impact the load time of nanonext or dependent packages.

Updates

• stop_aio() now causes the 'aio' to resolve to an 'errorValue' of 20 (Operation canceled) if successfully stopped.
• nng_error() now returns the error code combined with the message as a character string.
• Integer file descriptors are no longer appended to 'nanoSocket' attributes.
• Adds 'xz' to SystemRequirements (as was the case previously but not explicitly specified) (thanks @gaborcsardi).
• Re-aligns bundled 'libmbedtls' to v3.5.2 and optimises bundle size.
• Updates minimum 'libnng' version requirement to v1.6.0.
• Upgrades bundled 'libnng' to v1.8.0.
