How do I avoid unnecessary allocations in generic code?

In Go, avoiding unnecessary allocations in generic code requires careful consideration of data structures and memory usage. The use of interfaces, slices, and maps can lead to frequent allocations if not managed properly. Here are some strategies to help minimize allocations:

  • Reuse memory with sync.Pool for temporary objects.
  • Use value types instead of pointers where applicable.
  • Preallocate slices if the size is known ahead of time.
  • Implement custom types that allow for in-place modifications.

By adhering to these practices, you can write efficient generic code in Go that minimizes memory allocations.
