Involved Source Files Package nettrace contains internal hooks for tracing activity in the net package. This package is purely internal for use by the net/http/httptrace package and has no stable API exposed to end users.
Package-Level Type Names (total 3, all are exported)
/* sort exporteds by: | */
LookupIPAltResolverKey is a context.Context Value key used by tests to specify an alternate resolver func. It is not exposed to outsider users. (But see issue 12503) The value should be the same type as lookupIP: func lookupIP(ctx context.Context, host string) ([]IPAddr, error)
Trace contains a set of hooks for tracing events within the net package. Any specific hook may be nil. ConnectStart is called after a Dial with the results, excluding Dials made during DNS lookups. It may also be called multiple times, like ConnectStart. ConnectStart is called before a Dial, excluding Dials made during DNS lookups. In the case of DualStack (Happy Eyeballs) dialing, this may be called multiple times, from multiple goroutines. DNSDone is called after a DNS lookup completes (or fails). The coalesced parameter is whether singleflight de-duped the call. The addrs are of type net.IPAddr but can't actually be for circular dependency reasons. DNSStart is called with the hostname of a DNS lookup before it begins.
TraceKey is a context.Context Value key. Its associated value should be a *Trace struct.
