Structs

IterColumn

Wraps an iterator into a Column.

VecColumn

VecColumn provides Column over a slice.

Enums

FastFieldCodecType

Available codecs to use to encode the u64 (via MonotonicallyMappableToU64) converted data.

U128FastFieldCodecType

Available codecs to use to encode the u128 (via MonotonicallyMappableToU128) converted data.

Constants

ALL_CODEC_TYPES

The list of all available codecs for u64 convertible data.

Traits

Column

Column provides columnar access on a field.

MonotonicallyMappableToU64

Monotonic maps a value to u64 value space. Monotonic mapping enables PartialOrd on u64 space without conversion to original space.

MonotonicallyMappableToU128

Montonic maps a value to u128 value space Monotonic mapping enables PartialOrd on u128 space without conversion to original space.

StrictlyMonotonicFn

Values need to be strictly monotonic mapped to a Internal value (u64 or u128) that can be used in fast field codecs.

Functions

monotonic_map_column

Creates a view of a column transformed by a strictly monotonic mapping. See StrictlyMonotonicFn.

open

Returns the correct codec reader wrapped in the Arc for the data.

open_u128

Returns the correct codec reader wrapped in the Arc for the data.
