LookupRangeMode<'T> (Deedle)

LookupRangeMode<'T> Type

How `LookupRange` behaves on searchable virtual columns (quality / correctness axis).

Union case	Description
`LookupRangeExactFixed 'T -> int64 * int64` Full Usage: `LookupRangeExactFixed 'T -> int64 * int64` Parameters: Item : `'T -> int64 * int64`	Return a tight Fixed absolute index range for the searched value. Item : `'T -> int64 * int64`
`LookupRangeFullFixed` Full Usage: `LookupRangeFullFixed`	Naive over-approximation: entire ordinal domain (wrong for sparse matches).
`LookupRangeIndexList 'T -> int64 list` Full Usage: `LookupRangeIndexList 'T -> int64 list` Parameters: Item : `'T -> int64 list`	Precomputed absolute indices (irregular/sparse matches). Item : `'T -> int64 list`
`LookupRangeStep 'T -> int * int` Full Usage: `LookupRangeStep 'T -> int * int` Parameters: Item : `'T -> int * int`	Return a Custom strided range (offset, step) over the ordinal domain. Item : `'T -> int * int`
`LookupRangeUnsupported` Full Usage: `LookupRangeUnsupported`
