Package service manages connections between the VM application and the ALTS handshaker service.
package service

import (
	

	grpc 
)
mu guards hsConnMap and hsDialer.
hsConn represents a mapping from a hypervisor handshaker service address to a corresponding connection to a hypervisor handshaker service instance.
hsDialer will be reassigned in tests.
	hsDialer = grpc.Dial
)
Dial dials the handshake service in the hypervisor. If a connection has already been established, this function returns it. Otherwise, a new connection is created.
func ( string) (*grpc.ClientConn, error) {
	mu.Lock()
	defer mu.Unlock()

	,  := hsConnMap[]
Create a new connection to the handshaker service. Note that this connection stays open until the application is closed.
		var  error
		,  = hsDialer(, grpc.WithInsecure())
		if  != nil {
			return nil, 
		}
		hsConnMap[] = 
	}
