Struct State

pub struct State<I>
where
    I: Stream,
{
    pub position: <I::Item as Positioner>::Position,
    pub input: I,
}

The State<I> struct keeps track of the current position in the stream I

Fields

position: <I::Item as Positioner>::Position

input: I

Implementations

impl<I: Stream> State<I>

pub fn new(input: I) -> State<I>

pub fn as_empty(&self) -> State<I>

pub fn uncons(self) -> ParseResult<I::Item, I, I::Item>

uncons is the most general way of extracting and item from a stream It takes a function f as argument which should update the position according to the item that was extracted Usually you want to use uncons_char instead which works directly on character streams

pub fn update(self, i: I::Item, rest: I) -> ParseResult<I::Item, I, I::Item>

Trait Implementations

impl<I> Clone for State<I>

where I: Stream + Clone, I::Item: Clone,

fn clone(&self) -> State<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for State<I>

where I: Stream + Debug, <I::Item as Positioner>::Position: Debug,

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

Formats the value using the given formatter.

impl<I> PartialEq for State<I>

where I: Stream + PartialEq, I::Item: PartialEq,

fn eq(&self, other: &State<I>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<I> StructuralPartialEq for State<I>

where I: Stream,
