Package errors implements functions for handling errors It implements the same functions as the standard "errors" package, with a few added ones for ease of use Except where noted, functions that take a nil as their error will retrun nil, and do so very cheaply, so that you can use potentially expensive calls in main path. See godoc.org/errors for in-depth details about Is, As, Unwrap and New
