Limitations of Go generic functions: only type parameters are supported, value parameters are not supported. Function recursion is not supported. Type parameters cannot be specified explicitly, they are inferred by the compiler.
Restrictions of generic functions in Go language
Generic functions are a new feature in Go language. Allows us to create functions with type parameters that can be inferred at runtime. This allows us to write more versatile and reusable code.
However, generic functions in Go have some limitations:
Practical case
The following is a practical case using generic functions:
func Swap[T any](a, b *T) { tmp := *a *a = *b *b = tmp } func main() { a := 10 b := 20 Swap(&a, &b) fmt.Println(a, b) // 输出:20 10 }
In this example, Swap
The function is a generic function that accepts two pointers of type parameters T
. This function swaps the order of the two values passed to it. By using generics, we can call the Swap
function using different data types such as int
and string
.
Other limitations
In addition to the limitations listed above, generic functions have the following limitations:
int
and string
) as type parameters. The above is the detailed content of What are the limitations of generic functions in Golang?. For more information, please follow other related articles on the PHP Chinese website!
