Overview

Package ifaceassert defines an Analyzer that flags impossible interface-interface type assertions.

Analyzer ifaceassert

ifaceassert: detect impossible interface-to-interface type assertions

This checker flags type assertions v.(T) and corresponding type-switch cases in which the static type V of v is an interface that cannot possibly implement the target interface T. This occurs when V and T contain methods with the same name but different signatures. Example:

var v interface {
	Read()
}
_ = v.(io.Reader)

The Read method in v has a different signature than the Read method in io.Reader, so this assertion cannot succeed.
