metadata/metadata.go:59–66

New creates an MD from a given key-value map. Only the following ASCII characters are allowed in keys: - digits: 0-9 - uppercase letters: A-Z (normalized to lower) - lowercase letters: a-z - special characters: -_. Uppercase letters are automatically converted to lowercase. Keys beginning with "g

(m map[string]string)

// Keys beginning with "grpc-" are reserved for grpc-internal use only and may
// result in errors if set in metadata.
func New(m map[string]string) MD {
	md := make(MD, len(m))
	for k, val := range m {
		key := strings.ToLower(k)
		md[key] = append(md[key], val)
	}
	return md
}

// Pairs returns an MD formed by the mapping of key, value ...
// Pairs panics if len(kv) is odd.
