Struct ArrowSchema 

#[non_exhaustive]
pub struct ArrowSchema {
    pub serialized_schema: Bytes,
    /* private fields */
}

Arrow schema as specified in https://arrow.apache.org/docs/python/api/datatypes.html and serialized to bytes using IPC: https://arrow.apache.org/docs/format/Columnar.html#serialization-and-interprocess-communication-ipc

See code samples on how this message can be deserialized.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

serialized_schema: Bytes

IPC serialized Arrow schema.
