Derive Macro fluvio_protocol_derive::Encoder

#[derive(Encoder)]
{
    // Attributes available to this derive:
    #[varint]
    #[fluvio]
}

Custom derive for encoding structure or enum to bytes using Kafka protocol format. This assumes all fields(or enum variants) implement kafka encode traits.

Examples

use fluvio_protocol::Encoder;

#[derive(Encoder)]
pub struct SimpleRecord {
    val: u8
}

let mut data = vec![];

let record = SimpleRecord { val: 4 };
record.encode(&mut data,0);
     
assert_eq!(data[0],4);

Encoder applies to either Struct of Enum.

Encoder respects version attributes. See Decoder derive.
