soprintln

(Note: This is only useful when implementing the xgraph dynamic linking model, see https://github.com/bearcove/rubicon)

This crate provides the soprintln! macro, a debug variant of println! that:

  • Is disabled if the print feature cargo feature is not enabled
  • Is disabled if the SOPRINTLN environment variable isn't set to one
  • Prefixes the message with:
  • a truncated millisecond timestamp
  • a beacon of the shared object ID
  • a beacon of the thread name + ID

Beacons are 64-bit integers (can be initialized from pointers) whose color depend on their value. It makes it easier to spot the same value being re-used a bunch.
