go-iter

Package iter provides tools for creating iterators, for the Go programming language.

These iterators are intentionally made to resemble *sql.Rows from the "database/sql" package. Including having the same Close, Err, Next, and Scan methods.

(Note that to turn something into an actual *sql.Rows from the "database/sql" package, instead of just resembling it, use https://github.com/reiver/go-shunt instead.)

Documention

Online documentation, which includes examples, can be found at: http://godoc.org/github.com/reiver/go-iter

Example

var slice []string = []string {
	"apple",
	"banana",
	"cherry",
}

iterator := iterstring.Slice{
	Slice: slice,
}

defer iterator.Close()

for iterator.Next() {

	var datum string // Could have also used: var datum interface{}

	if err := iterator.Decode(&datum); nil != err {
		return err
	}

	fmt.Printf("Next datum: %v \n", datum)
}
if err := iterator.Err(); nil != err {
	return err
}
