func Of ¶

func Of[E any](e E) *E

Of creates a pointer to the provided value of type 'E'. The primary purpose of this function is to simplify the creation of pointers to values without needing to use temporary variables.

Copy hazard: the argument is passed by value, so Of returns a pointer to a fresh copy, not to the caller's original variable. Do not use Of with types that must not be copied after first use (e.g. sync.Mutex, sync.WaitGroup, strings.Builder, or any struct embedding such a type, including g's *Mutex/*RwLock/*Builder) — the copy may carry stale internal state and `go vet` will not flag it here. Take the address of the original value instead.

Parameters:

e: The value of type 'E' to create a pointer for.

Returns:

*E: A pointer to a copy of the provided value 'e'.

Example usage:

intValue := 42
intPtr := ref.Of(intValue)
fmt.Println(*intPtr)
