Struct arrow::ipc::gen::Schema::Feature [−][src]
#[repr(transparent)]pub struct Feature(pub i64);
Expand description
Represents Arrow Features that might not have full support within implementations. This is intended to be used in two scenarios:
- A mechanism for readers of Arrow Streams and files to understand that the stream or file makes use of a feature that isn’t supported or unknown to the implementation (and therefore can meet the Arrow forward compatibility guarantees).
- A means of negotiating between a client and server what features a stream is allowed to use. The enums values here are intented to represent higher level features, additional details maybe negotiated with key-value pairs specific to the protocol.
Enums added to this list should be assigned power-of-two values to facilitate exchanging and comparing bitmaps for supported features.
Tuple Fields
0: i64
Implementations
The stream makes use of multiple full dictionaries with the same ID and assumes clients implement dictionary replacement correctly.
The stream makes use of compressed bodies as described in Message.fbs.
Returns the variant’s name or “” if unknown.
