What does this statement mean in Go:
Student.bookMap=map[string][]*model.Books{}
Where Student is:
type Student struct{
bookMap map[string][]*model.Books
}
and we have a model package
package model
type Books struct {
bookName string `db:"Name"`
bookAuthor string `db:"Author"`
}
That statement is initializing the map Student.bookMap to an empty map (which has the following structure: key -> string, value -> slice of pointers of model.Books).
It means the member bookMap of a struct Student contains a map which takes a string as a key, and an array (slice) of pointers to instances of model.Books as value.
