// GRPC_CUSTOM_SERVER_METADATA.
|

// Each of these is a comma-prefixed and comma-separated list of metadata types

// that will be added to ClientMetadata and ServerMetadata respectively.

// Different sites with internal grpc-core extensions can substitute this file

// with fast metadata types of their own.
