Struct Slice 

pub struct Slice { /* private fields */ }

RFC 9535 array slice selector with streaming-compatible semantics.

Negative bounds and negative steps are intentionally not represented here: those require knowing the array length before matching can be correct. A zero step is represented and simply matches no array elements.

Implementations

impl Slice

pub const fn new(start: Option<usize>, end: Option<usize>, step: usize) -> Slice

Creates a slice selector.

pub const fn start(self) -> Option<usize>

Inclusive start bound, or None for the default start.

pub const fn end(self) -> Option<usize>

Exclusive end bound, or None for an open-ended slice.

pub const fn step(self) -> usize

Step size. A zero step matches no elements.

pub fn contains(self, index: usize) -> bool

Returns whether this slice includes index.

Trait Implementations

impl Clone for Slice

fn clone(&self) -> Slice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Slice

impl Debug for Slice

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

Formats the value using the given formatter.

impl Eq for Slice

impl Hash for Slice

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

where __H: Hasher,

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 Slice

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

Tests for self and other values to be equal, and is used by ==.

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

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