Trait Implementations

impl<I: Debug + Input> Debug for Pear<I>

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

Formats the value using the given formatter.

impl<I: Input> Deref for Pear<I>

type Target = I

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<I: Input> DerefMut for Pear<I>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<I: Input> From<I> for Pear<I>

fn from(input: I) -> Pear<I>

Converts to this type from the input type.

impl<I: Input> Input for Pear<I>

type Token = <I as Input>::Token

type Slice = <I as Input>::Slice

type Many = <I as Input>::Many

type Marker = <I as Input>::Marker

type Context = <I as Input>::Context

fn token(&mut self) -> Option<Self::Token>

Returns a copy of the current token, if there is one.

fn slice(&mut self, n: usize) -> Option<Self::Slice>

Returns a copy of the current slice of size n, if there is one.

fn has(&mut self, n: usize) -> bool

Returns true if there are at least n tokens remaining.

fn peek<F>(&mut self, cond: F) -> bool

where F: FnMut(&Self::Token) -> bool,

Checks if the current token fulfills cond.

fn peek_slice<F>(&mut self, n: usize, cond: F) -> bool

where F: FnMut(&Self::Slice) -> bool,

Checks if the current slice of size n (if any) fulfills cond.

fn eat<F>(&mut self, cond: F) -> Option<Self::Token>

where F: FnMut(&Self::Token) -> bool,

Checks if the current token fulfills cond. If so, the token is consumed and returned. Otherwise, returns None.

fn eat_slice<F>(&mut self, n: usize, cond: F) -> Option<Self::Slice>

where F: FnMut(&Self::Slice) -> bool,

Checks if the current slice of size n (if any) fulfills cond. If so, the slice is consumed and returned. Otherwise, returns None.

fn take<F>(&mut self, cond: F) -> Self::Many

where F: FnMut(&Self::Token) -> bool,

Takes tokens while cond returns true, collecting them into a Self::Many and returning it.

fn skip<F>(&mut self, cond: F) -> usize

where F: FnMut(&Self::Token) -> bool,

Skips tokens while cond returns true. Returns the number of skipped tokens.

fn mark(&mut self, info: &ParserInfo) -> Self::Marker

Emits a marker that represents the current parse position.

fn context(&mut self, mark: Self::Marker) -> Self::Context

Returns a context to identify the input spanning from mark until but excluding the current position.

impl<I: Input + Rewind> Rewind for Pear<I>

fn rewind_to(&mut self, marker: Self::Marker)

Resets self to the position identified by marker.
