Decoded column data from a segment scan.

Variants

Int64

Fields

values: Vec<i64>

valid: Vec<bool>

Float64

Fields

values: Vec<f64>

valid: Vec<bool>

Timestamp

Fields

values: Vec<i64>

valid: Vec<bool>

Bool

Fields

values: Vec<bool>

valid: Vec<bool>

Binary

Variable-length or fixed-size binary (String, Bytes, Geometry, Decimal, Uuid, Vector).

Fields

data: Vec<u8>

Raw decompressed bytes for the block.

offsets: Vec<u32>

Per-row byte offsets into data. Length = row_count + 1.

valid: Vec<bool>

DictEncoded

Dictionary-encoded string column.

IDs index into dictionary. Use dictionary[ids[i]] to recover the string for row i when valid[i] is true.

Fields

ids: Vec<u32>

Symbol IDs per row (index into dictionary).

dictionary: Vec<String>

Dictionary: ID → string value. Populated from ColumnMeta.dictionary.

valid: Vec<bool>

Trait Implementations
