Implementations

impl Array

pub fn new(shape: Vec<usize>, data: Data) -> Array

pub fn scalar_i64(v: i64) -> Array

pub fn scalar_f64(v: f64) -> Array

pub fn scalar_bool(v: bool) -> Array

pub fn from_i64(values: Vec<i64>) -> Array

pub fn from_f64(values: Vec<f64>) -> Array

pub fn from_chars(values: Vec<char>) -> Array

pub fn empty(dtype: DType) -> Array

pub fn boxed(value: Array) -> Array

y as a scalar box (J <).

pub fn box_fill() -> Array

The element that fills a boxed array: J’s a:, a box holding an empty numeric list.

pub fn dtype(&self) -> DType

pub fn rank(&self) -> usize

pub fn count(&self) -> usize

Total number of elements.

pub fn items(&self) -> usize

Number of items (major cells): leading axis length, 1 for a scalar.

pub fn item_size(&self) -> usize

Elements per item.

pub fn cast(&self, to: DType) -> Option<Array>

pub fn cells(&self, frame_rank: usize) -> Vec<Array>

Split into cells: the trailing cell_rank axes form the cell shape, the leading axes form the frame.

pub fn cell_at(&self, frame_rank: usize, index: usize) -> Array

One cell without materialising all of them.

pub fn item(&self, i: usize) -> Array

Item i (major cell along the leading axis).

pub fn as_i64_slice(&self) -> Option<&[i64]>

pub fn as_boxes(&self) -> Option<&[Array]>

The boxed elements, if the array holds boxes.

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

pub fn as_ext_slice(&self) -> Option<&[Ext]>

The extended integers, if the array holds them.

pub fn as_rat_slice(&self) -> Option<&[Rat]>

The rationals, if the array holds them.

pub fn as_complex_slice(&self) -> Option<&[Cx]>

pub fn to_complex_vec(&self) -> Option<Vec<Cx>>

Numeric contents widened to complex. None for character or boxed data.

pub fn to_f64_vec(&self) -> Option<Vec<f64>>

Numeric contents widened to f64. None for character data.

pub fn to_i64_vec(&self) -> Option<Vec<i64>>

Numeric contents as i64 if exactly representable.
