Struct thin_str::ThinStr

#[repr(transparent)]
pub struct ThinStr(_);

Like a Box, but only a single pointer.

use thin_str::ThinStr;
let s = ThinStr::new("abcde");
assert_eq!(s.len(), 5);
let t: ThinStr = "foo".into();
assert_ne!(t, s);
let q = s.clone();
assert_eq!(s, q);

Methods

impl ThinStr

pub const fn empty() -> Self

Create a new empty string.

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

Create a new string with the same contents as s.

pub fn new_zeroed(len: usize) -> Self

Create a new string with all bytes initialized to zero.

pub fn len(&self) -> usize

How long is the string, in bytes.

pub fn is_empty(&self) -> bool

Returns true if the len is zero.

pub fn to_string(&self) -> String

We can't specialize the real to_string, but at least we can help out people whose muscle memory for -> String is 'call to_string()'

pub fn as_bytes(&self) -> &[u8]

Access the string's byte array.

pub unsafe fn as_mut_bytes(&mut self) -> &mut [u8]

Get the underlying byte array mutably. It's unsound to write into this unless you ensure that it remains valid UTF8 after your writes.

Safety

Caller must not write non-utf8 bytes

pub fn as_mut_str(&mut self) -> &mut str

pub fn as_str(&self) -> &str
