Method ConfirmUsable

tools/clientcmd/client_config.go:341–370

ConfirmUsable looks a particular context and determines if that particular part of the config is useable. There might still be errors in the config, but no errors in the sections requested or referenced. It does not return early so that it can find as many errors as possible.
