Struct Columns 

Source 
pub struct Columns {
    pub oid: FixedSizeBinaryArray,
    pub offset: UInt64Array,
    pub len: UInt64Array,
    pub obj_type: UInt8Array,
    pub size: UInt64Array,
    pub delta_base: UInt64Array,
}
Expand description

The six Arrow arrays that carry the five facts, in oid-lexicographic order. The byte extent is one fact in two columns because that is what it is — (offset, len) — and splitting it lets a scan of just the offsets stay contiguous.

Fields§

§oid: FixedSizeBinaryArray§offset: UInt64Array§len: UInt64Array§obj_type: UInt8Array§size: UInt64Array§delta_base: UInt64Array

Archive offset of the base entry, 0 for none. Same coordinate space as offset, which is what makes a whole-column comparison against the offset column meaningful (a delta’s base is an entry in this table).
