1// Package errdefs defines a set of error interfaces that packages should use for communicating classes of errors. 2// Errors that cross the package boundary should implement one (and only one) of these interfaces. 3// 4// Packages should not reference these interfaces directly, only implement them. 5// To check if a particular error implements one of these interfaces, there are helper 6// functions provided (e.g. `Is<SomeError>`) which can be used rather than asserting the interfaces directly. 7// If you must assert on these interfaces, be sure to check the causal chain (`err.Cause()`). 8package errdefs // import "github.com/docker/docker/errdefs" 9
