pub struct MzOffset {
pub offset: u64,
}
Expand description
Universal language for describing message positions in Materialize, in a source independent way. Individual sources like Kafka or File sources should explicitly implement their own offset type that converts to/From MzOffsets. A 0-MzOffset denotes an empty stream.
Fields
offset: u64
