mbyio / sloghelpers

Utilities for Go's stdlib slog logging library.

This module contains helpers for the log/slog package. https://pkg.go.dev/log/slog

Right now I am just copy-and-pasting helpers as I write/use them in my own projects. Please let me know if you are using this module yourself or if you have any suggestions for improvements.
