Struct fastobo::syntax::Lexer

pub struct Lexer;

The OBO format version 1.4 lexer.

Implementations

impl OboLexer

pub fn tokenize(rule: Rule, input: &str) -> Result<Pairs<'_, Rule>, Error<Rule>>

Tokenize an input string using the given production rule.

This is basically a specialized version of pest::Parser::parse that only accepts Rule, and does not need the Parser trait to be in scope.

pub fn tokenize_all( rule: Rule, input: &str ) -> Result<Pairs<'_, Rule>, Error<Rule>>

Tokenize the entirety of an input string.

Contrary to OboLexer::tokenize, this method will return an error if if the input is not parsed in its entirety.

Trait Implementations

impl Debug for OboLexer

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

Formats the value using the given formatter.

impl Parser<Rule> for OboLexer

fn parse<'i>(rule: Rule, input: &'i str) -> Result<Pairs<'i, Rule>, Error<Rule>>

Parses a &str starting from rule.
