Note: After adding entries to this table, run 'go generate runtime/metrics' to update the runtime/metrics doc comment. (Otherwise the runtime/metrics test will fail.)

Note: After adding entries to this table, update the list in doc/godebug.md as well. (Otherwise the test in this package will fail.)

Types

type Info

type Info struct {
	Name    string // name of the setting ("panicnil")
	Package string // package that uses the setting ("runtime")
	Changed int    // minor version when default changed, if any; 21 means Go 1.21
	Old     string // value that restores behavior prior to Changed
	Opaque  bool   // setting does not export information to runtime/metrics using [github.com/go-asm/go/godebug.Setting.IncNonDefault]
}

An Info describes a single known GODEBUG setting.

func Lookup

func Lookup(name string) *Info

Lookup returns the Info with the given name.
