    // Provided methods

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

Trait for types that can back an ALTLOGICAL vector.

Required Methods

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

Get the logical element at index i.

Provided Methods

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

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

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

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

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).
