Struct SparseIterLogicalData 

pub struct SparseIterLogicalData<I: Iterator<Item = bool>> {
    state: SparseIterState<I, bool>,
}

Sparse iterator-backed logical vector data adaptor.

Fields

state: SparseIterState<I, bool>

Implementations

impl<I: Iterator<Item = bool>> SparseIterLogicalData<I>

pub fn from_iter(iter: I, len: usize) -> Self

Create from an iterator with explicit length.

impl<I: ExactSizeIterator<Item = bool>> SparseIterLogicalData<I>

pub fn from_exact_iter(iter: I) -> Self

Create from an ExactSizeIterator (length auto-detected).

Trait Implementations

impl<I: Iterator<Item = bool>> AltLogicalData for SparseIterLogicalData<I>

fn elt(&self, i: usize) -> Logical

Get the logical element at index i.

fn get_region(&self, start: usize, len: usize, buf: &mut [i32]) -> usize

Optional: bulk read into buffer (clamped to available data).

fn as_r_slice(&self) -> Option<&[i32]>

Optional: return a slice if data is contiguous i32 (R’s internal format).

fn is_sorted(&self) -> Option<Sortedness>

Optional: sortedness hint.

fn no_na(&self) -> Option<bool>

Optional: does this vector contain any NA values?

fn sum(&self, _na_rm: bool) -> Option<i64>

Optional: optimized sum (count of TRUE values).

impl<I: Iterator<Item = bool>> AltrepLen for SparseIterLogicalData<I>

fn len(&self) -> usize

Returns the length of this ALTREP vector.

fn is_empty(&self) -> bool

Returns true if the vector is empty.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
