Struct IterRealCoerceData 

pub struct IterRealCoerceData<I, T>
where
    I: Iterator<Item = T>,
    T: Coerce<f64> + Copy,
{
    state: IterState<I, T>,
}

Iterator-backed real vector data adaptor with coercion from any float-like type.

Wraps an iterator producing values that coerce to f64 (e.g., f32, integer types).

Example

use miniextendr_api::altrep_data::IterRealCoerceData;

// Create from an iterator of f32 values
let iter = (0..5).map(|x| x as f32 * 1.5);
let data = IterRealCoerceData::from_iter(iter, 5);
// Values are coerced from f32 to f64 when accessed

Fields

state: IterState<I, T>

Trait Implementations

impl<I, T> AltRealData for IterRealCoerceData<I, T>

where I: Iterator<Item = T>, T: Coerce<f64> + Copy,

fn elt(&self, i: usize) -> f64

Get the real element at index i.

fn as_slice(&self) -> Option<&[f64]>

Optional: return a pointer to contiguous data if available.

fn get_region(&self, start: usize, len: usize, buf: &mut [f64]) -> 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<f64>

Optional: optimized sum.

fn min(&self, _na_rm: bool) -> Option<f64>

Optional: optimized min.

fn max(&self, _na_rm: bool) -> Option<f64>

Optional: optimized max.

impl<I, T> AltrepLen for IterRealCoerceData<I, T>

where I: Iterator<Item = T>, T: Coerce<f64> + Copy,

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.
