IOHandle is a small library that provides ergonomic type-safe error handling for cats-effect IO.

It is based on cats-mtl's Handle and Raise capabilities, but specialized for cats.effect.IO with some additional safety.

• "Submarine Error Handling" PR in cats-mtl
  • Difference: IOHandle library aims to provide additional safety/debugging, for example when the Raise/Handle instance is leaked outside its original scope
• ValdemarGr's catch-effect library
  • Difference: We rely on IO.raiseError instead of IO cancellation
