Struct SpanParser 

pub struct SpanParser<'a> { /* private fields */ }

Implementations

impl<'a> SpanParser<'a>

pub fn then_span(self, other: SpanParser<'a>) -> SpanParser<'a>

Sequential composition: flattens nested Seq chains into a single Vec.

pub fn or(self, other: SpanParser<'a>) -> SpanParser<'a>

Alternation: flattens nested OneOf chains into a single Vec.

pub fn opt_span(self) -> SpanParser<'a>

pub fn many_span(self, bounds: impl RangeBounds<usize> + 'a) -> SpanParser<'a>

pub fn sep_by_span( self, sep: SpanParser<'a>, bounds: impl RangeBounds<usize> + 'a, ) -> SpanParser<'a>

pub fn sep_by_ws_span( self, sep: SpanParser<'a>, bounds: impl RangeBounds<usize> + 'a, ) -> SpanParser<'a>

Fused sep_by + whitespace trimming: single trim between each step.

pub fn wrap_span( self, left: SpanParser<'a>, right: SpanParser<'a>, ) -> SpanParser<'a>

pub fn skip_span(self, next: SpanParser<'a>) -> SpanParser<'a>

pub fn next_after(self, next: SpanParser<'a>) -> SpanParser<'a>

pub fn not_span(self, negated: SpanParser<'a>) -> SpanParser<'a>

pub fn minus_span(self, excluded: SpanParser<'a>) -> SpanParser<'a>

Set difference: match self only if excluded would NOT match at the same starting position. Used for EBNF/BNF exception (-) semantics.

pub fn look_ahead_span(self, lookahead: SpanParser<'a>) -> SpanParser<'a>

pub fn negate_span(self) -> SpanParser<'a>

Zero-width negative assertion: succeeds (empty Span) when inner fails.

pub fn peek_span(self) -> SpanParser<'a>

Zero-width positive assertion: succeeds with inner’s Span but does NOT consume input. The dual of negate_span().

pub fn trim_whitespace(self) -> SpanParser<'a>

pub fn save_state(self) -> SpanParser<'a>

pub fn into_parser(self) -> Parser<'a, Span<'a>>

Convert to a generic Parser<'a, Span<'a>>.

pub fn map<O: 'a>(self, f: fn(Span<'a>) -> O) -> Parser<'a, O>

Map Span output to any type, producing a generic Parser.

pub fn map_closure<O: 'a>(self, f: impl Fn(Span<'a>) -> O + 'a) -> Parser<'a, O>

Map with a closure (not just fn pointer).

impl<'a> SpanParser<'a>

pub fn call(&self, state: &mut ParserState<'a>) -> Option<Span<'a>>

Trait Implementations

impl<'a> BitOr for SpanParser<'a>

type Output = SpanParser<'a>

The resulting type after applying the | operator.

fn bitor(self, other: SpanParser<'a>) -> Self::Output

Performs the | operation.

impl<'a> From<SpanParser<'a>> for Parser<'a, Span<'a>>

fn from(sp: SpanParser<'a>) -> Self

Converts to this type from the input type.
