// 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()`).
