Struct abi_stable::std_types::StaticSlice

#[repr(C)]
pub struct StaticSlice<T: 'static> { /* fields omitted */ }

Wrapper type around &'static [T] as a workaround for the non-stable-constness of <[T]>::len.

Once <[T]>::len is stable in const contests define the RSlice::from_slice const fn so as to replace this type with RSlice<'static,T>.

Example

use abi_stable::std_types::StaticSlice;

const SLICE:StaticSlice<u32>=StaticSlice::new(&[11,12,13,14]);

assert_eq!(&SLICE[..], &[11,12,13,14]);

Methods

impl<T: 'static> StaticSlice<T>

pub const fn new(s: &'static [T]) -> Self

Creates a StaticSlice<T> from a &'static [T]

Example

use abi_stable::std_types::StaticSlice;

let slic=StaticSlice::new(&[0,1,2,3]);

assert_eq!(&*slic,&[0,1,2,3]);

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

Gets the &'static [Y] back.

Example

use abi_stable::std_types::StaticSlice;

let slic=StaticSlice::new(&[-1,-2,-3,-4]);

assert_eq!(slic.as_slice(),&[-1,-2,-3,-4]);

Important traits for RSlice<'a, u8>

impl<'a> Read for RSlice<'a, u8>

pub fn as_rslice(&self) -> RSlice<'static, T>

Converts the internal &'static [T] into a RSlice<'static,T>.

Example

use abi_stable::std_types::{RSlice,StaticSlice};

let slic=StaticSlice::new(&[-1,-2,-3,-4]);

assert_eq!(slic.as_rslice(), RSlice::from_slice(&[-1,-2,-3,-4]));
