Struct yew_ansi::CharCursor

pub struct CharCursor<'a> { /* fields omitted */ }

Cursor for characters in a string slice.

Implementations

impl<'a> CharCursor<'a>

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

Create a cursor for the given slice. The cursor starts at the start of the slice.

pub fn position(&self) -> usize

Get the cursor's position in the slice. This will always point to a valid char boundary.

pub fn get<I: SliceIndex<str>>(&self, i: I) -> Option<&'a I::Output>

Index the contained string slice. The index isn't bound by the cursor's position, only by the underlying slice.

pub fn remainder(&self) -> &'a str

Get a string slice containing all the characters following the current position.

pub fn peek_char(&self, expected: char) -> bool

Check if the next character matches the expected one. This doesn't advance the cursor's position.

pub fn read(&mut self) -> Option<char>

Read the next character and advance the cursor.

pub fn read_char(&mut self, expected: char) -> Option<char>

Read the next character and advance the cursor only if it matches the expected one. Returns None if the character didn't match.

pub fn read_while(&mut self, f: impl FnMut(char) -> bool)

Advance the cursor while the given function returns true. The cursor won't advance if the function returns false.

Trait Implementations

impl<'a> Clone for CharCursor<'a>

fn clone(&self) -> CharCursor<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for CharCursor<'a>

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

Formats the value using the given formatter.
