Struct zerotrie::builder::konst::store::ConstSlice

pub(crate) struct ConstSlice<'a, T> {
    full_slice: &'a [T],
    start: usize,
    limit: usize,
}

A const-friendly slice type. It is backed by a full slice but is primarily intended to represent subslices of the full slice. We need this only because we can’t take subslices in const Rust.

Fields

full_slice: &'a [T]

The full slice.

start: usize

The start index of the slice represented by this ConstSlice.

limit: usize

The non-inclusive end index of the slice represented by this ConstSlice.

Implementations

impl<'a, T> ConstSlice<'a, T>

pub const fn from_slice(other: &'a [T]) -> Self

Creates a ConstSlice representing an entire slice.

pub const fn from_manual_slice( full_slice: &'a [T], start: usize, limit: usize, ) -> Self

Creates a ConstSlice with the given start and limit.

pub const fn len(&self) -> usize

Returns the length of the ConstSlice.

pub const fn get_or_panic(&self, index: usize) -> &T

Gets the element at index, panicking if not present.

pub const fn last(&self) -> Option<&T>

Gets the last element or None if empty.

pub fn as_slice(&self) -> &'a [T]

Non-const function that returns this ConstSlice as a regular slice.

Trait Implementations

impl<'a, T: Clone> Clone for ConstSlice<'a, T>

fn clone(&self) -> ConstSlice<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for ConstSlice<'a, T>

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

Formats the value using the given formatter.

impl<'a, T> From<&'a [T]> for ConstSlice<'a, T>

fn from(other: &'a [T]) -> Self

Converts to this type from the input type.
