| `Field(field_name, &class::field, m)` | The same as the two-parameter version, but provides a better error message. |
| `Key(e)` | `argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`. |
| `Pair(m1, m2)` | `argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
-| `FieldsAre(m...)` | `argument` is a compatible object where each field matches piecewise with `m...`. A compatible object is any that supports the `std::tuple_size<Obj>`+`get<I>(obj)` protocol. In C++17 and up this also supports types compatible with structured bindings, like aggregates. |

| `Property(&class::property, m)` | `argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. The method `property()` must take no argument and be declared as `const`. |

**Notes:**
+* You can use `FieldsAre()` to match any type that supports structured
+ bindings, such as `std::tuple`, `std::pair`, `std::array`, and aggregate
+ types. For example:
+
+ ```cpp
+ std::tuple<int, std::string> my_tuple{7, "hello world"};
+ EXPECT_THAT(my_tuple, FieldsAre(Ge(0), HasSubstr("hello")));
+
+ struct MyStruct {
+ int value = 42;
+ std::string greeting = "aloha";
+ };
+ MyStruct s;
+ EXPECT_THAT(s, FieldsAre(42, "aloha"));
+ ```
+
* Don't use `Property()` against member functions that you do not own, because
taking addresses of functions is fragile and generally not part of the
contract of the function.
