Struct ndarray::Si

pub struct Si(pub Ixs, pub Option<Ixs>, pub Ixs);

A slice, a description of a range of an array axis.

Fields are begin, end and stride, where negative begin or end indexes are counted from the back of the axis.

If end is None, the slice extends to the end of the axis.

Examples

Si(0, None, 1) is the full range of an axis. Python equivalent is [:].

Si(a, Some(b), 2) is every second element from a until b. Python equivalent is [a:b:2].

Si(a, None, -1) is every element, in reverse order, from a until the end. Python equivalent is [a::-1]

Tuple Fields

0: Ixs

1: Option<Ixs>

2: Ixs

Implementations

impl Si

pub fn from<R: SliceRange>(r: R) -> Self

pub fn step(self, step: Ixs) -> Self

Trait Implementations

impl Clone for Si

fn clone(&self) -> Si

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Si

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

Formats the value using the given formatter.

impl Hash for Si

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Si

fn eq(&self, other: &Si) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
