go - Checking the equality of two slices

How can I check if two slices are equal?

Answer

You need to loop over each of the elements in the slice and test. Equality for slices is not defined. However, there is a bytes.Equal function if you are comparing values of type []byte.

func testEq(a, b []Type) bool {

    // If one is nil, the other must also be nil.

    if (a == nil) != (b == nil) { 
        return false; 
    }

    if len(a) != len(b) {
        return false
    }

    for i := range a {
        if a[i] != b[i] {

            return false
        }
    }

    return true
}
