Package logging is an auto-generated package for the Stackdriver Logging API. NOTE: This package is in alpha. It is not stable, and is likely to change. Writes log entries and manages your Logging configuration. Use of Context The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them. To close the open connection, use the Close() method. For information about setting deadlines, reusing contexts, and more please visit godoc.org/cloud.google.com/go. Use the client at cloud.google.com/go/logging in preference to this.

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

func DefaultAuthScopes() []string {
	return []string{

}

versionGo returns the Go runtime version. The returned string has no whitespace, suitable for reporting in header.

func versionGo() string {
	const develPrefix = "devel +"

	s := runtime.Version()
	if strings.HasPrefix(s, develPrefix) {
		s = s[len(develPrefix):]
		if p := strings.IndexFunc(s, unicode.IsSpace); p >= 0 {
			s = s[:p]
		}
		return s
	}

	notSemverRune := func(r rune) bool {
		return strings.IndexRune("0123456789.", r) < 0
	}

	if strings.HasPrefix(s, "go1") {
		s = s[2:]
		var prerelease string
		if p := strings.IndexFunc(s, notSemverRune); p >= 0 {
			s, prerelease = s[:p], s[p:]
		}
		if strings.HasSuffix(s, ".") {
			s += "0"
		} else if strings.Count(s, ".") < 2 {
			s += ".0"
		}
		if prerelease != "" {
			s += "-" + prerelease
		}
		return s
	}
	return "UNKNOWN"
