Contains data structures and utilities for handling gRPC custom metadata.
Modules§
- The metadata::errors module contains types for errors that can occur while handling gRPC custom metadata.
Structs§
- A view to all values stored in a single entry.
MetadataMap
entry iterator.MetadataMap
entry iterator.- An iterator over
MetadataMap
keys. - Represents a custom metadata field name.
- A set of gRPC custom metadata entries.
- Represents a custom metadata field value.
- A view into a single occupied location in a
MetadataMap
. - A view into a single empty location in a
MetadataMap
. - A drain iterator of all values associated with a single metadata key.
- An iterator of all values associated with a single metadata key.
MetadataMap
value iterator.MetadataMap
value iterator.
Enums§
- gRPC metadata values can be either ASCII strings or binary. Note that only visible ASCII characters (32-127) are permitted. This type should never be instantiated – in fact, it’s impossible to, because there’s no variants to instantiate. Instead, it’s just used as a type parameter for
MetadataKey
andMetadataValue
