Package stdmethods defines an Analyzer that checks for misspellings in the signatures of methods similar to well-known interfaces.

Analyzer stdmethods

stdmethods: check signature of methods of well-known interfaces

Sometimes a type may be intended to satisfy an interface but may fail to do so because of a mistake in its method signature. For example, the result of this WriteTo method should be (int64, error), not error, to satisfy io.WriterTo: 

type myWriterTo struct{...}
func (myWriterTo) WriteTo(w io.Writer) error { ... }

This check ensures that each method whose name matches one of several well-known interface methods from the standard library has the correct signature for that interface.

Checked method names include: 

Format GobEncode GobDecode MarshalJSON MarshalXML
Peek ReadByte ReadFrom ReadRune Scan Seek
UnmarshalJSON UnreadByte UnreadRune WriteByte
WriteTo
