proxy.golang.org: github.com/google/go-cmp/cmp

Package cmp determines equality of values. This package is intended to be a more powerful and safer alternative to reflect.DeepEqual for comparing whether two values are semantically equal. It is intended to only be used in tests, as performance is not a goal and it may panic if it cannot compare the values. Its propensity towards panicking means that its unsuitable for production environments where a spurious panic may be fatal. The primary features of cmp are: When the default behavior of equality does not suit the test's needs, 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 with an Equal method (e.g., time.Time.Equal) 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 by default; they result in panics unless suppressed by using an Ignore option (see github.com/google/go-cmp/cmp/cmpopts.IgnoreUnexported) or explicitly compared using the Exporter option.

proxy.golang.org: github.com/google/go-cmp/cmp/internal/diff

Package diff implements an algorithm for producing edit-scripts. The edit-script is a sequence of operations needed to transform one list of symbols into another (or vice-versa). The edits allowed are insertions, deletions, and modifications. The summation of all edits is called the Levenshtein distance as this problem is well-known in computer science. This package prioritizes performance over accuracy. That is, the run time is more important than obtaining a minimal Levenshtein distance.
