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

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

RleLayout

Which RLE stream layout the encoder should produce.

RleMeta

Metadata for RLE decoding, one variant per RleLayout.

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.
