Struct Matcher 

pub struct Matcher { /* private fields */ }

Implementations

impl Matcher

pub fn new( pattern: Pattern, disambiguation: Disambiguation, size_limit: usize, ) -> Self

pub fn new_with_backend( pattern: Pattern, disambiguation: Disambiguation, size_limit: usize, backend: Backend, ) -> Self

pub fn pattern(&self) -> &Pattern

pub const fn disambiguation(&self) -> Disambiguation

pub fn lowering(&self) -> &Lowering

pub fn pool(&self) -> &IrPool

pub fn parse_value(&mut self, input: &str) -> Result<Value, MatchError>

Parse an entire input and reconstruct its typed IR value.

Errors

Returns MatchError::NoMatch when the selected backend rejects the input, and MatchError::SizeLimitExceeded on recognition or value-reconstruction exhaustion.

pub fn parse(&mut self, input: &str) -> Result<ParseTree, MatchError>

Parse an entire input and expose the derivation in AST vocabulary.

Errors

Returns MatchError::NoMatch if the entire input is not in the pattern’s language, and MatchError::SizeLimitExceeded on resource exhaustion.

pub fn find_parse( &mut self, input: &str, ) -> Result<Option<ParseTree>, MatchError>

Find and parse the leftmost-longest matching substring.

Errors

Returns MatchError::SizeLimitExceeded if the matching-state limit is exceeded.

pub fn try_is_match(&mut self, input: &str) -> Result<bool, MatchError>

Check an entire input without discarding resource-limit failures.

Errors

Returns MatchError::SizeLimitExceeded if the matching-state limit is exceeded.

pub fn is_match(&mut self, input: &str) -> bool

pub fn trace(&mut self, input: &str) -> Vec<TraceStep>
