Struct ParserCheckpoint

pub struct ParserCheckpoint { /* private fields */ }

Represents a point during the Parser’s lifecycle; retaining state that can then be rewound.

Don’t use this directly, instead retrieve a checkpoint with Parser::checkpoint() and rewind the parser to a checkpoint with Parser::rewind().

Trait Implementations

impl Clone for ParserCheckpoint

fn clone(&self) -> ParserCheckpoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParserCheckpoint

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

Formats the value using the given formatter.

impl Default for ParserCheckpoint

fn default() -> ParserCheckpoint

Returns the “default value” for a type.

impl From<ParserCheckpoint> for Cursor

fn from(value: ParserCheckpoint) -> Self

Converts to this type from the input type.

impl From<ParserCheckpoint> for Kind

fn from(value: ParserCheckpoint) -> Self

Converts to this type from the input type.

impl From<ParserCheckpoint> for Token

fn from(value: ParserCheckpoint) -> Self

Converts to this type from the input type.

impl Hash for ParserCheckpoint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ParserCheckpoint

fn cmp(&self, other: &ParserCheckpoint) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ParserCheckpoint

fn eq(&self, other: &ParserCheckpoint) -> 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 PartialOrd for ParserCheckpoint

fn partial_cmp(&self, other: &ParserCheckpoint) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ToSpan for ParserCheckpoint

fn to_span(&self) -> Span

impl Copy for ParserCheckpoint

impl Eq for ParserCheckpoint
