Overview ¶
Package conn provides the representation of a logical connection. A connection is the primitive used for load balancing by the github.com/bufbuild/httplb package. A single connection generally wraps a single transport (or http.RoundTripper) to a single resolved address.

type Conn ¶
type Conn interface { // RoundTrip sends a request using this connection. This is the same as // [http.RoundTripper]'s method of the same name except that it accepts // a callback that, if non-nil, is invoked when the request is completed. RoundTrip(req *http.Request, whenDone func()) (*http.Response, error) // Scheme returns the URL scheme to use with this connection. Scheme() string // Address is the address to which this value is connected. Address() resolver.Address // UpdateAttributes updates the connection's address to have the given attributes. UpdateAttributes(attributes attribute.Values) // Prewarm attempts to pre-warm this connection. Not all transports support // this operation. For those that do not, calling this function is a no-op. // It returns an error if the given context is cancelled or times out before // the connection can finish warming up. Prewarm(context.Context) error }
Conn represents a connection to a resolved address. It is a *logical* connection. It may actually be represented by zero or more physical connections (i.e. sockets).
