| // Package errdefs defines a set of error interfaces that packages should use for communicating classes of errors. | |
| // Errors that cross the package boundary should implement one (and only one) of these interfaces. | |
| // | |
| // Packages should not reference these interfaces directly, only implement them. | |
| // To check if a particular error implements one of these interfaces, there are helper | |
| // functions provided (e.g. `Is<SomeError>`) which can be used rather than asserting the interfaces directly. | |
| // If you must assert on these interfaces, be sure to check the causal chain (`err.Cause()`). | |
