Module wire 

Wire-level encoding metadata — for tile analysis and tooling.

These types describe the physical and logical encoding of streams inside an MLT tile. Normal tile consumers (parse → iterate features) do not need this module; it is intended for tools that inspect or report encoding statistics.

Structs

IntEncoding

Morton

Metadata for Morton decoding

RleMeta

Metadata for RLE decoding TODO v2 optimizations:

StreamMeta

Metadata about an encoded stream

Enums

ColumnType

Column data type, as stored in the tile

DictionaryType

Dictionary type used for a column, as stored in the tile

LengthType

Length type used for a column, as stored in the tile

LogicalEncoding

How should the stream be interpreted at the logical level (second pass of decoding)

LogicalTechnique

Logical encoding technique used for a column, as stored in the tile

OffsetType

Offset type used for a column, as stored in the tile

PhysicalEncoding

Physical encoding used for a column, as stored in the tile

StatType

What to calculate with Analyze::collect_statistic.

StreamType

How should the stream be interpreted at the physical level (first pass of decoding)

Traits

Analyze

Trait for estimating various size/count metrics.
