Enum DataArray 

pub enum DataArray {
    Float32(Vec<f32>),
    Float64(Vec<f64>),
}

Adaptive array wrapper: holds HEALPix data in the native FITS precision.

This avoids unnecessary conversions when source data is f32. All operations convert on-demand to f64 only when needed.

Variants

Float32(Vec<f32>)

32-bit float data (saves memory for typical HEALPix maps)

Float64(Vec<f64>)

64-bit float data (for high-precision maps)

Implementations

impl DataArray

pub fn from_f32(data: Vec<f32>) -> Self

Create a Float32 array from data

pub fn from_f64(data: Vec<f64>) -> Self

Create a Float64 array from data

pub fn len(&self) -> usize

Get array length

pub fn is_empty(&self) -> bool

Check if array is empty

pub fn get(&self, idx: usize) -> Option<f64>

Get element as f64 (converts on-demand if f32)

pub fn iter(&self) -> impl Iterator<Item = f64> + '_

Iterate over values as f64

pub fn min_value(&self) -> f64

Compute min value, skipping UNSEEN/NaN

pub fn max_value(&self) -> f64

Compute max value, skipping UNSEEN/NaN

pub fn valid_f64_values(&self) -> Vec<f64>

Collect valid values as f64 vector for percentile/statistics

pub fn as_f64_vec(&self) -> Cow<'_, Vec<f64>>

Get underlying f64 vec if this is Float64, otherwise convert

Used for compatibility with existing code that expects Vec<f64>. For f32 data, this allocates a new vector with conversions.

pub fn as_f64_slice(&self) -> Option<&[f64]>

Get as f64 slice if Float64, otherwise panics

Used in performance-critical hot loops where we want f64 slice directly. For code that needs to work with both types, use as_f64_vec() instead.

pub fn memory_size_bytes(&self) -> usize

Get memory size in bytes

pub fn dtype(&self) -> &'static str

Get data type name for debugging/logging
