Module matchers

Modules

• collection
  The collection module contains matchers for asserting properties of collections and iterators.
• variant
  The variant module contains matchers for asserting properties of enums and convienience functions for Option and Result.

Macros

• all_of
  Takes a list of matchers for the same type combines them conjunctively.
• any_of
  Takes a list of matchers for the same type combines them disjunctively.
• has_structure
  Write patterns of structs/enums which use Matchers instead of field values.
• structure
  Shorter name for has_structure!.

Structs

• All
  A Matcher struct which joins multiple Matchers conjunctively.
• Any
  A Matcher struct which joins multiple Matchers disjunctively.

Functions

• any_value
  A matcher which always matches.
• assertion_always_fails
  A matcher which never matches.
• assertion_always_succeeds
  A matcher which always matches.
• close_to
  Matches if the asserted value is in an epsilon range around the expected value.
• eq
  Matches if the asserted value is equal to the expected value.
• equal_to
  Matches if the asserted value is equal to the expected value.
• geq
  Matches if the asserted value is greater than or equal to the expected value.
• greater_than
  Matches if the asserted value is greater than the expected value.
• greater_than_or_equal
  Matches if the asserted value is greater than or equal to the expected value.
• gt
  Matches if the asserted value is greater than the expected value.
• has
  Accepts a matcher and returns it unmodified.
• is
  Accepts a matcher and returns it unmodified.
• leq
  Matches if the asserted value is less than or equal to the expected value.
• less_than
  Matches if the asserted value is less than the expected value.
• less_than_or_equal
  Matches if the asserted value is less than or equal to the expected value.
• lt
  Matches if the asserted value is less than the expected value.
• no_value
  A matcher which never matches.
• not
  A matcher negating the result of the passed matcher.
• same_object
  Matches if asserted value and the expected value are truely the same object.
