Source§impl Str32
impl Str32
Sourcepub fn as_mut_str(&mut self) -> &mut str
pub fn as_mut_str(&mut self) -> &mut str
Convert a &mut Str32 to a &mut str slice.
Sourcepub const fn as_bytes(&self) -> &[u8] ⓘ
pub const fn as_bytes(&self) -> &[u8] ⓘ
Converts the Str32 to a byte slice.
§Examples
let s: &Str32 = "123".try_into().unwrap();
assert_eq!(b"123", s.as_bytes());Sourcepub unsafe fn as_bytes_mut(&mut self) -> &mut [u8] ⓘ
pub unsafe fn as_bytes_mut(&mut self) -> &mut [u8] ⓘ
Converts the Str32 to a byte slice.
§Examples
let mut s = String32::try_from("123").unwrap();
let bytes = unsafe { s.as_bytes_mut() };
assert_eq!(b"123", bytes);§Safety
See str::as_bytes_mut.
Sourcepub fn as_mut_ptr(&mut self) -> *mut u8
pub fn as_mut_ptr(&mut self) -> *mut u8

Returns an iterator over the ASCII-whitespace-delimited words of a &Str32.
Sourcepub fn split_at(&self, mid: u32) -> (&Self, &Self)
pub fn split_at(&self, mid: u32) -> (&Self, &Self)
Splits a &Str32 in two at the given byte index.
§Panics
Panics if mid is not a UTF-8 code point boundary.
Sourcepub fn split_at_mut(&mut self, mid: u32) -> (&mut Self, &mut Self)
pub fn split_at_mut(&mut self, mid: u32) -> (&mut Self, &mut Self)

pub fn split_whitespace(&self) -> impl DoubleEndedIterator<Item = &Self> + '_
Returns an iterator over the whitespace-delimited words of a &Str32.
Sourcepub fn eq_ignore_ascii_case(&self, other: &Self) -> bool
pub fn eq_ignore_ascii_case(&self, other: &Self) -> bool
Checks if two string slices are equal, ignoring ASCII case mismatches.
Sourcepub fn escape_debug(&self) -> EscapeDebug<'_>
pub fn escape_debug(&self) -> EscapeDebug<'_>
Return an iterator over the string slice’s chars, each escaped according to char::escape_debug.
Sourcepub fn escape_default(&self) -> EscapeDefault<'_>

pub fn is_char_boundary(&self, index: u32) -> bool
Returns whether the given index corresponds to a char boundary.
Sourcepub fn make_ascii_lowercase(&mut self)
pub fn make_ascii_lowercase(&mut self)

§Examples
let mut s = String32::try_from("ABC").unwrap();
s.make_ascii_lowercase();
assert_eq!("abc", s);Sourcepub fn make_ascii_uppercase(&mut self)
pub fn make_ascii_uppercase(&mut self)
