LookupRangeExecutor (Deedle) | Deedle

LookupRangeExecutor Module

Namespace: Deedle.Virtual
Assembly: Deedle.dll

Shared LookupRange / GetSubVector logic for ordinal virtual sources.

Types

Type	Description
SubVectorSpec<'T>	Sub-vector plan: callers compose `valueAt << MapRow` so OptionalValue sources stay typed.

Functions and values

Function or value	Description
`LookupRangeExecutor.clipLookupRange mode lo newLen` Full Usage: `LookupRangeExecutor.clipLookupRange mode lo newLen` Parameters: mode : `LookupRangeMode<'T>` lo : `int64` newLen : `int64` Returns: `LookupRangeMode<'T>` Type parameters: 'T	mode : `LookupRangeMode<'T>` lo : `int64` newLen : `int64` Returns: `LookupRangeMode<'T>`
`LookupRangeExecutor.getSubVector length mode asLong range` Full Usage: `LookupRangeExecutor.getSubVector length mode asLong range` Parameters: length : `int64` mode : `LookupRangeMode<'T>` asLong : `('T -> int64) option` range : `RangeRestriction<Address>` Returns: `Choice<SubVectorSpec<'T>, 'a>` Type parameters: 'T, 'a	length : `int64` mode : `LookupRangeMode<'T>` asLong : `('T -> int64) option` range : `RangeRestriction<Address>` Returns: `Choice<SubVectorSpec<'T>, 'a>`
`LookupRangeExecutor.intersect a b` Full Usage: `LookupRangeExecutor.intersect a b` Parameters: a : `RangeRestriction<Address>` b : `RangeRestriction<Address>` Returns: `RangeRestriction<Address>`	Intersect two LookupRange results (same original address domain). Used to fuse two `filterRowsBy` predicates into one sub-vector restriction. Never enumerates [`StepRange`] (its enumerator throws by design). a : `RangeRestriction<Address>` b : `RangeRestriction<Address>` Returns: `RangeRestriction<Address>`
`LookupRangeExecutor.lookupRange length mode value context` Full Usage: `LookupRangeExecutor.lookupRange length mode value context` Parameters: length : `int64` mode : `LookupRangeMode<'T>` value : `'T` context : `string` Returns: `RangeRestriction<Address>` Type parameters: 'T	length : `int64` mode : `LookupRangeMode<'T>` value : `'T` context : `string` Returns: `RangeRestriction<Address>`
