T for which an implicit Normalization[T] exists.

one or both objects, then comparing the results using an “after normalization” equality referenced from
the afterNormalizationEquality member.

one or both objects, then comparing the results using an “after normalization” Equivalence referenced from
the afterNormalizationEquivalence member.

Option, which converts Some to Good,
None to Bad.

object, to transform that object into a String representation.

can be useful for debug and log messages about program state.
Trait that provides a snap method that takes one or more arguments and results in a
SnapshotSeq, whose toString lists the names
and values of each argument.
Provides methods that produce Uniformity[String] instances for various
ways to normalize strings for equality comparisons.
Trait providing an implicit conversion that adds a times method to Ints that
will repeat a given side-effecting operation multiple times.
Trait containing an implicit conversion that adds a +- method to Numeric types, which enables
spreads to be expressed in terms of a pivot and tolerance.
Provides Equality and Equivalence instances for Numeric types that
compare for equality with a given tolerance.
Provides three implicit methods that loosen the equality constraint defined by TypeCheckedTripleEquals or ConversionCheckedTripleEquals
for Scala Traversables to one that more closely matches Scala's approach to Traversable equality.
Provides === and !== operators that return Boolean, delegate the equality determination
to an Equality type class, and require no relationship between the types of the two values compared.
Trait that defines abstract methods used to enforce compile-time type constraints for equality comparisons, and defines === and !== operators
used by matchers.
Trait providing an implicit class that adds a toOr method to
Try, which converts Success to Good,
and Failure to Bad.
Provides === and !== operators that return Boolean, delegate the equality determination
to an Equality type class, and require the types of the two values compared to be in a subtype/supertype
relationship.
Defines a custom way to normalize instances of a type that can also handle normalization of that type when passed as Any.
Represents the result of a validation, either the object Pass if the validation
succeeded, else an instance of Fail containing an error value describing the validation failure.
Provides === and !== operators that return Boolean, delegate the equality determination
to an Equality type class, and require that either the types of the two values compared are in a subtype/supertype
relationship, or that an implicit conversion is available that can convert from one type to the other.
Provides === and !== operators that return Boolean, delegate the equality determination
to an Equality type class, and require no relationship between the types of the two values compared.
