Function AddConfig

fs/filter/filter.go:707–713

AddConfig returns a mutable config structure based on a shallow copy of that found in ctx and returns a new context with that added to it.

(ctx context.Context)

// copy of that found in ctx and returns a new context with that added
// to it.
func AddConfig(ctx context.Context) (context.Context, *Filter) {
	c := GetConfig(ctx)
	cCopy := new(Filter)
	*cCopy = *c
	newCtx := context.WithValue(ctx, configContextKey, cCopy)
	return newCtx, cCopy
}

// ReplaceConfig replaces the filter config in the ctx with the one
// passed in and returns a new context with that added to it.
