Trait Slices

pub trait Slices<'a, T>: Clone
where
    T: 'a,
{
    // Required methods
    fn empty() -> Self;
    fn num_slices(&self) -> usize;
    fn slices(&self) -> impl Iterator<Item = &'a [T]>;
    fn lengths(&self) -> impl Iterator<Item = usize>;
    fn slice_at(&self, f: usize) -> Option<&'a [T]>;
    unsafe fn slice_at_unchecked(&self, f: usize) -> &'a [T];
}

A collection of slices.

Required Methods

fn empty() -> Self

Creates an empty collection of slices.

fn num_slices(&self) -> usize

Number of slices.

fn slices(&self) -> impl Iterator<Item = &'a [T]>

Iterator over slices.

fn lengths(&self) -> impl Iterator<Item = usize>

Iterator over lengths of slices.

fn slice_at(&self, f: usize) -> Option<&'a [T]>

Returns a reference to the f-th slice. Returns None if out of bounds.

unsafe fn slice_at_unchecked(&self, f: usize) -> &'a [T]

Returns the f-th slice without bounds checks.

Safety

The caller must ensure that f < self.num_slices().

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
