Struct Wtf8Atom
pub struct Wtf8Atom { /* private fields */ }Available on crate features
__ecma and ecma_ast only.Expand description
A WTF-8 encoded atom. This is like Atom, but can contain unpaired surrogates.
Implementations§
Methods from Deref<Target = Wtf8>§
pub fn slice(&self, begin: usize, end: usize) -> &Wtf8
pub fn slice(&self, begin: usize, end: usize) -> &Wtf8
Return a slice of the given string for the byte range [begin..end).
§Failure
Fails when begin and end do not point to code point boundaries,
or point beyond the end of the string.
pub fn slice_from(&self, begin: usize) -> &Wtf8
pub fn slice_from(&self, begin: usize) -> &Wtf8
Return a slice of the given string from byte begin to its end.
§Failure
Fails when begin is not at a code point boundary,
or is beyond the end of the string.
pub fn slice_to(&self, end: usize) -> &Wtf8
pub fn slice_to(&self, end: usize) -> &Wtf8
Return a slice of the given string from its beginning to byte end.
§Failure
Fails when end is not at a code point boundary,
or is beyond the end of the string.
pub fn ascii_byte_at(&self, position: usize) -> u8
pub fn ascii_byte_at(&self, position: usize) -> u8
Return the code point at position if it is in the ASCII range,
or `b’\xFF’ otherwise.
§Failure
Fails if position is beyond the end of the string.
pub fn code_points(&self) -> Wtf8CodePoints<'_> ⓘ
pub fn code_points(&self) -> Wtf8CodePoints<'_> ⓘ
Return an iterator for the string’s code points.
pub fn as_str(&self) -> Option<&str>
pub fn as_str(&self) -> Option<&str>
Try to convert the string to UTF-8 and return a &str slice.
Return None if the string contains surrogates.
This does not copy the data.
pub fn to_string_lossy(&self) -> Cow<'_, str>
pub fn to_string_lossy(&self) -> Cow<'_, str>
Lossily convert the string to UTF-8.
Return an UTF-8 &str slice if the contents are well-formed in UTF-8.
Surrogates are replaced with "\u{FFFD}" (the replacement character
“�”).
This only copies the data if necessary (if it contains any surrogate).
pub fn to_ill_formed_utf16(&self) -> IllFormedUtf16CodeUnits<'_> ⓘ
pub fn to_ill_formed_utf16(&self) -> IllFormedUtf16CodeUnits<'_> ⓘ
Convert the WTF-8 string to potentially ill-formed UTF-16 and return an iterator of 16-bit code units.
This is lossless:
calling Wtf8Buf::from_ill_formed_utf16 on the resulting code units
would always return the original WTF-8 string.
