Types ¶
type Builder ¶
type Builder struct {
// contains filtered or unexported fields
}
Builder creates gRPC-based Transports. It must be paired with ServerIdentifiers that contain an Extension field of type ServerIdentifierExtension.
func NewBuilder ¶
NewBuilder provides a builder for creating gRPC-based Transports using the credentials from provided map of credentials names to credentials.Bundle.
type Config ¶
type Config struct {
// Credentials is the credentials bundle to be used for the connection.
Credentials credentials.Bundle
// GRPCNewClient is an optional custom function to establish a gRPC connection.
// If nil, grpc.NewClient will be used as the default.
GRPCNewClient func(target string, opts ...grpc.DialOption) (*grpc.ClientConn, error)
}
Config defines the configuration for connecting to a gRPC server, including credentials and an optional custom new client function.
type ServerIdentifierExtension ¶
type ServerIdentifierExtension struct {
// ConfigName is the name of the configuration to use for this transport.
// It must be present as a key in the map of configs passed to NewBuilder.
ConfigName string
}
ServerIdentifierExtension holds settings for connecting to a gRPC server, such as an xDS management or an LRS server.
It must be set by value (not pointer) in the clients.ServerIdentifier.Extensions field (See Example).
Example ¶
ExampleServerIdentifierExtension demonstrates how to create clients.ServerIdentifier with grpctransport.ServerIdentifierExtension as its extensions.
This example is creating clients.ServerIdentifier to connect to server at localhost:5678 using the config named "local". Note that "local" must exist as an entry in the provided configs to grpctransport.Builder.
package main
import (
"fmt"
"google.golang.org/grpc/internal/xds/clients"
"google.golang.org/grpc/internal/xds/clients/grpctransport"
)
func main() {
// Note the Extensions field is set by value and not by pointer.
fmt.Printf("%+v", clients.ServerIdentifier{ServerURI: "localhost:5678", Extensions: grpctransport.ServerIdentifierExtension{ConfigName: "local"}})
}
Output: {ServerURI:localhost:5678 Extensions:{ConfigName:local}}
