Definitions of the assertions that are provided by this crate.
Assertions define the methods that are used to assert that the actual test result is as expected. Assertions are defined by traits that are implemented for one or several types. An assertion can be applied to all types that implement this assertion.
All assertions provided by this crate are defined in this module. Browse over the traits in this module to get information about all provided assertions.
