Struct NpyMaskedArray 

pub struct NpyMaskedArray {
    pub data: Vec<f64>,
    pub mask: Vec<bool>,
    pub fill_value: f64,
    pub shape: Vec<usize>,
}

A masked NumPy-style array: elements where mask[i] is true are considered invalid/missing (following NumPy ma conventions).

Fields

data: Vec<f64>

Underlying data.

mask: Vec<bool>

Per-element mask. true = masked (invalid).

fill_value: f64

Fill value used when accessing masked elements.

shape: Vec<usize>

Shape of the array.

Implementations

impl NpyMaskedArray

pub fn new( data: Vec<f64>, mask: Vec<bool>, shape: Vec<usize>, fill_value: f64, ) -> Result<Self, String>

Create a masked array from data and mask.

pub fn from_data(data: Vec<f64>, shape: Vec<usize>) -> Result<Self, String>

Create with all elements unmasked.

pub fn get_filled(&self, idx: usize) -> f64

Get element, returning fill_value if masked.

pub fn count_valid(&self) -> usize

Number of valid (unmasked) elements.

pub fn mean_valid(&self) -> Option<f64>

Mean of valid (unmasked) elements. Returns None if all masked.

pub fn filled(&self) -> Vec<f64>

Fill masked values with fill_value and return a plain Vecf64`.

pub fn mask_greater_than(&mut self, threshold: f64)

Apply a threshold mask: mask elements where |data\[i\]| > threshold.

pub fn unmask_all(&mut self)

Unmask all elements.

Trait Implementations

impl Clone for NpyMaskedArray

Performs copy-assignment from source.

impl Debug for NpyMaskedArray

fn fmt(&self, f: &mut Formatter<'_>) -> Result
