Trait Implementations

impl<'a> CharFormat<'a> for UTF8

type Iter = CharIndices<'a>

Iterator for characters and their byte indices.

unsafe fn char_indices(buf: &'a [u8]) -> CharIndices<'a>

Iterate over the characters of the string and their byte indices.

fn encode_char<F>(ch: char, cont: F) -> Result<(), ()>

where F: FnOnce(&[u8]),

Encode the character as bytes and pass them to a continuation.

impl Clone for UTF8

fn clone(&self) -> UTF8

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UTF8

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for UTF8

fn default() -> UTF8

Returns the “default value” for a type.

impl Format for UTF8

fn validate(buf: &[u8]) -> bool

Check whether the buffer is valid for this format.

fn validate_prefix(buf: &[u8]) -> bool

Check whether the buffer is valid for this format.

fn validate_suffix(buf: &[u8]) -> bool

Check whether the buffer is valid for this format.

fn validate_subseq(buf: &[u8]) -> bool

Check whether the buffer is valid for this format.

unsafe fn fixup(_lhs: &[u8], _rhs: &[u8]) -> Fixup

Compute any fixup needed when concatenating buffers.

impl SliceExt<UTF8> for str

fn to_tendril(&self) -> Tendril<F>

Make a Tendril from this slice.

impl SliceFormat for UTF8

type Slice = str

impl SubsetOf<UTF8> for ASCII

fn revalidate_subset(x: &[u8]) -> bool

Validate the other direction of conversion; check if this buffer from the superset format conforms to the subset format.

impl SubsetOf<WTF8> for UTF8

fn revalidate_subset(x: &[u8]) -> bool

Validate the other direction of conversion; check if this buffer from the superset format conforms to the subset format.

impl<Sink: TreeSink> TendrilSink<UTF8> for Parser<Sink>

type Output = <Sink as TreeSink>::Output

What the overall result of processing is.

fn process(&mut self, t: StrTendril)

Process this tendril.

fn error(&mut self, desc: Cow<'static, str>)

Indicates that an error has occurred.

fn finish(self) -> Self::Output

Indicates the end of the stream.

fn one<T>(self, t: T) -> Self::Output

where Self: Sized, T: Into<Tendril<F, A>>,

Process one tendril and finish.

fn from_iter<I>(self, i: I) -> Self::Output

where Self: Sized, I: IntoIterator, <I as IntoIterator>::Item: Into<Tendril<F, A>>,

Consume an iterator of tendrils, processing each item, then finish.

fn read_from<R>(self, r: &mut R) -> Result<Self::Output, Error>

where Self: Sized, R: Read, F: SliceFormat<Slice = [u8]>,

Read from the given stream of bytes until exhaustion and process incrementally, then finish. Return Err at the first I/O error.

fn from_file<P>(self, path: P) -> Result<Self::Output, Error>

where Self: Sized, P: AsRef<Path>, F: SliceFormat<Slice = [u8]>,

Read from the file at the given path and process incrementally, then finish. Return Err at the first I/O error.
