Trait nalgebra::base::SliceRange

pub trait SliceRange<D: Dim> {
    type Size: Dim;
    fn begin(&self, shape: D) -> usize;
    fn end(&self, shape: D) -> usize;
    fn size(&self, shape: D) -> Self::Size;
}

A range with a size that may be known at compile-time.

This may be:

• A single usize index, e.g., 4
• A left-open range std::ops::RangeTo, e.g., .. 4
• A right-open range std::ops::RangeFrom, e.g., 4 ..
• A full range std::ops::RangeFull, e.g., ..

Associated Types

type Size: Dim

Type of the range size. May be a type-level integer.

Required methods

fn begin(&self, shape: D) -> usize

The start index of the range.

fn end(&self, shape: D) -> usize

The index immediately after the last index inside of the range.

fn size(&self, shape: D) -> Self::Size

The number of elements of the range, i.e., self.end - self.begin.
