Add Last helper method (#6)
It is very common for FilterPath functions to operate on the last step
in a path. However, it is a hindrance to continually write:
if len(p) == 0 {
return false
}
return p[len(p)-1].Type() == ...
Instead, add a helper method Last that avoids the empty path check
and the indexing to the last element.
This allows users to simply write:
return p.Last().Type() == ...
This is more readable and writeable.
This package is intended to be a more powerful and safer alternative to reflect.DeepEqual for comparing whether two values are semantically equal.
The primary features of cmp are:
When the default behavior of equality does not suit the needs of the test, custom equality functions can override the equality operation. For example, an equality function may report floats as equal so long as they are within some tolerance of each other.
Types that have an Equal method may use that method to determine equality. This allows package authors to determine the equality operation for the types that they define.
If no custom equality functions are used and no Equal method is defined, equality is determined by recursively comparing the primitive kinds on both values, much like reflect.DeepEqual. Unlike reflect.DeepEqual, unexported fields are not compared; they result in panics unless suppressed by using an Ignore option.
This is not an official Google product.
