Struct abi_stable::std_types::static_str::StaticStr

#[repr(C)]
pub struct StaticStr { /* fields omitted */ }

Wrapper type around &'static str as a workaround for the non-stable-constness of str::len.

Example

use abi_stable::std_types::StaticStr;

const STR:StaticStr=StaticStr::new("foo");

assert_eq!(&STR[..], "foo");

Methods

impl StaticStr

pub const fn new(s: &'static str) -> Self

Creates a StaticStr from a &'static str

Example

use abi_stable::std_types::StaticStr;

const BAR:StaticStr=StaticStr::new("bar");

assert_eq!(&*BAR, "bar");

pub fn as_str(&self) -> &'static str

Gets the &'static str back.

Example

use abi_stable::std_types::StaticStr;

const NOM:StaticStr=StaticStr::new("baz");

assert_eq!(NOM.as_str(), "baz");

pub fn as_rstr(&self) -> RStr<'static>

Converts the internal &'static str into a RStr<'static>.

Example

use abi_stable::std_types::{RStr,StaticStr};

const PARSEC:StaticStr=StaticStr::new("{}");

assert_eq!(PARSEC.as_rstr(), RStr::from("{}"));
