Package for equality of Go values
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
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
Equalmethod 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
Equalmethod is defined, equality is determined by recursively comparing the primitive kinds on both values, much like
reflect.DeepEqual, unexported fields are not compared by default; they result in panics unless suppressed by using an
cmpopts.IgnoreUnexported) or explicitly compared using the
