| Package `metautils` provides convenience functions for dealing with gRPC metadata.MD objects inside |
| Context handlers. |
| |
| While the upstream grpc-go package contains decent functionality (see https://github.com/grpc/grpc-go/blob/master/Documentation/grpc-metadata.md) |
| they are hard to use. |
| |
| The majority of functions center around the NiceMD, which is a convenience wrapper around metadata.MD. For example |
| the following code allows you to easily extract incoming metadata (server handler) and put it into a new client context |
| metadata. |
| |
| nmd := metautils.ExtractIncoming(serverCtx).Clone(":authorization", ":custom") |
| clientCtx := nmd.Set("x-client-header", "2").Set("x-another", "3").ToOutgoing(ctx) |
