[go-nuts] Questions about struct conversion

Hi all, I confronted with a confusing problem regarding struct conversion. See https://play.golang.org/p/n6NfjsthHP The declarations of PrivateKey and PublicKey are copied from crypto/rsa, but the code can not be compiled. It can be compiled successfully if the embedded field PublicKey is repla

You are redeclaring the package type. When converting type, the conversion semantics is simply mytype(a) and conversion occurs if the rule that you mention is respected. I suppose that you need to have your own struct to store date, with a different name everything works. The package type is inde
