What’s the problem?

slog-gin currently stores its per-request ID under a private key:

const requestIDCtx = "slog-gin.request-id"

Because it’s unexported, anyone who wants to pull that ID out of a plain context.Context must hard-code the string literal, leading to brittle, “stringly-typed” code.

Why can’t I just use GetRequestID?

func GetRequestID(c *gin.Context) string

That helper only works with a Gin *gin.Context. In many architectures—where inner layers deal only in context.Context—you can’t import or depend on Gin types.

Happy to open a PR if this sounds reasonable!
