Metadata.AsciiMarshaller (grpc-all 1.69.0 API)

Enclosing class:

Metadata
```
public static interface Metadata.AsciiMarshaller<T>
```
Marshaller for metadata values that are serialized into ASCII strings. The strings contain only following characters:
- Space: 0x20, but must not be at the beginning or at the end of the value. Leading or trailing whitespace may not be preserved.
- ASCII visible characters (0x21-0x7E).
Note this has to be the subset of valid characters in field-content from RFC 7230 Section 3.2.
