This issue can be caused by several factors, including using a pointer to a struct instead of a copy of the struct, or failing to properly pass a pointer to a function that updates the struct. To ensure that the receiver pointer of a custom struct is updated, make sure to use a pointer to the struct when passing it to a function and ensure that the function updates the struct through the pointer. For example:
go
Copy code
type MyStruct struct {
data int
}
func (s *MyStruct) UpdateData(newData int) {
s.data = newData
}
func main() {
s := &MyStruct{data: 1}
s.UpdateData(10)
fmt.Println(s.data)
}
This will output 10, indicating that the receiver pointer of the custom struct was successfully updated.
Additionally, it's important to keep in mind that Go is a pass-by-value language, meaning that when you pass a struct to a function, a copy of the struct is created. To update the original struct, you must pass a pointer to the struct, which points to the memory address where the struct is stored, allowing you to modify the original struct.
If you're still having issues with your receiver pointer not updating, try checking the scope of your variables, and making sure that you're passing a pointer to the correct instance of the struct, rather than a new instance of the struct or a copy of the struct.
If you can provide more details or code that demonstrates the issue, I may be able to provide a more specific solution.
