Struct lib_ruby_parser::Parser

pub struct Parser {
    pub yylexer: Lexer,
    pub yydebug: bool,
    pub static_env: StaticEnvironment,
    // some fields omitted
}

A Bison parser, automatically generated from src/parser.y.

Fields

yylexer: Lexer

Lexer that is used to get tokens

yydebug: bool

Boolean field that enables printing shift/reduce actions during parsing

static_env: StaticEnvironment

Stack of sets of variables in current scopes. Each stack item represents locals in the scope.

You can use it to pre-define some locals and parse your input as if these locals exist.

For example, you can parse the following code

a = b + c

as

Send(LocalVar(a), "+", LocalVar(b))

by declaring a and b as locals using

parser.static_env.declare("a")
parser.static_env.declare("b")
parser.parse()

Implementations

impl Parser

pub fn parse(&mut self) -> bool

Parses given input. Returns true if the parsing was successful.

impl Parser

pub fn new<TInput>(input: TInput, options: ParserOptions) -> Self where
    TInput: Into<Vec<u8>>, 

Constructs a parser with given input and options.

Returns an error if given input is invalid.

pub fn do_parse(self) -> ParserResult

Parses given input and returns:

1. AST
2. tokens
3. diagnostics
4. coments
5. magic comments

Trait Implementations

impl Debug for Parser

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

Formats the value using the given formatter.
