Implementations

impl Input

pub fn new(text: impl ToString) -> Self

pub fn start(&mut self) -> ModifyInput<'_>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn rest(&self) -> &str

pub fn prev_slice_bytes(&self, bytes: usize) -> StrSlice

pub fn bump(&mut self, bytes: usize) -> StrSlice

pub fn peek_char(&self) -> Option<char>

pub fn prev_char(&self) -> Option<char>

pub fn parse<P: Parse>(&mut self, parser: P) -> Option<P::Output>

This parses the specified parser and returns the result. If it fails, None is returned. For correctness, the parser should NOT be bumped if None is returned.

pub fn parse_i<P: ParseInfallible>(&mut self, parser: P) -> P::Output

This parses the specified parser and returns the result. The parser can’t fail.

pub fn try_parse<P: Parse>(&mut self, parser: P)

This tries to parse the specified parser. If it doesn’t succeed, nothing happens.

pub fn can_parse<P: Parse>(&mut self, parser: P) -> bool

This returns whether the parser can be successfully parsed. For correctness, the parser should NOT be bumped.

Trait Implementations

impl Clone for Input

fn clone(&self) -> Input

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Input

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

Formats the value using the given formatter.

impl Index<StrSlice> for Input

type Output = str

The returned type after indexing.

fn index(&self, index: StrSlice) -> &Self::Output

Performs the indexing (container[index]) operation.
