Struct ScannerBuilder

pub struct ScannerBuilder { /* private fields */ }

A builder for creating a scanner.

Implementations

impl ScannerBuilder

pub fn new() -> Self

Creates a new scanner builder.

pub fn add_patterns<P, S>(self, patterns: P) -> SimpleScannerBuilder

where P: IntoIterator<Item = S>, S: AsRef<str>,

Adds only patterns to the scanner builder. This is useful for simple use cases where only one scanner mode is needed. The scanner mode is named INITIAL implicitly. Adding more scanner modes as well as transitions between scanner modes are not supported. Note that all previously added scanner modes will be ignored after calling this method.

pub fn add_scanner_mode(self, scanner_mode: ScannerMode) -> Self

Adds a scanner mode to the scanner builder.

pub fn add_scanner_modes(self, scanner_modes: &[ScannerMode]) -> Self

Adds multiple scanner modes to the scanner builder.

pub fn use_nfa(self) -> Self

Sets the scanner to use an NFA instead of a DFA.

pub fn build(self) -> Result<Scanner>

Builds the scanner from the scanner builder.
