Struct Span

pub struct Span<'a>(/* private fields */);
Expand description

A marker produced by SliceCache that ensures that all resulting Spans will be mutually non-overlapping.

§Examples

let mut cache = SliceCache::new(4, |span| {
    Box::new([span])
});

Implementations§

§

impl<'a> Span<'a>

pub fn slice<R>(&self, range: R) -> Option<Span<'a>>
where R: RangeBounds<usize>,

cache span at mid. Analogous to slice::split_at.

§Examples
let mut cache = SliceCache::new(4, |span| {
    let (left, right) = span.split_at(2);
    Box::new([left, right])
});

pub fn split_at(&self, mid: usize) -> (Span<'a>, Span<'a>)

cache span at mid. Analogous to slice::split_at.

§Examples
let mut cache = SliceCache::new(4, |span| {
    let (left, right) = span.split_at(2);
    Box::new([left, right])
});

pub fn chunks(self, chunk_size: usize) -> Chunks<'a>

Returns an Iterator over chunk_size elements of thr slice. Analogous to slice::chunks.

§Examples
let mut cache = SliceCache::new(4, |span| {
    span.chunks(2).collect()
});
