go pkg

Some simple Go toolkits to help speed up daily development.

Some of them were copied from well-known projects because I think their dependencies are too extensive, and many of them are not useful to me. Or I have made modifications to these codes, such as using generics

• bizerror encapsulates code and msg into errors, providing asynchronous error callbacks and error stack printing.
• context
  • without_cancel cancels the parent context but keeps keys and values, consistent with WithoutCancel in go1.21
• copy
  • deepcopy supports deep copy of generics, implemented based on reflection
• grpc
  • middleware-chain
  • context-wrappers
• logs which You can use it directly without initialization
  • zap logger
• routine opens a goroutine to recover the panic automatically
