// SafePtr is a function that takes a pointer of any type (T) as an argument.
|
|
// If the provided pointer is not nil, it returns the same pointer. If it is nil, it returns nil instead.
|
|
//
|
|
// This function is particularly useful to prevent nil pointer dereferencing when:
|
|
//
|
|
// - The type implements interfaces that are called by the logger, such as `fmt.Stringer`.
|
|
// - And these interface implementations do not perform nil checks themselves.
