Struct SequenceArray 

pub struct SequenceArray { /* private fields */ }

Represents the equation A[i] = a * i + b. This can be used for compression, fast comparisons and also for row ids. An array representing the equation A[i] = base + i * multiplier.

Implementations

impl SequenceArray

pub fn typed_new<T: NativePType + Into<PValue>>( base: T, multiplier: T, nullability: Nullability, length: usize, ) -> VortexResult<Self>

pub fn new( base: PValue, multiplier: PValue, ptype: PType, nullability: Nullability, length: usize, ) -> VortexResult<Self>

Constructs a sequence array using two integer values (with the same ptype).

pub fn ptype(&self) -> PType

pub fn base(&self) -> PValue

pub fn multiplier(&self) -> PValue

pub fn last(&self) -> PValue

Returns the validated final value of a sequence array
