Struct Parser 

pub struct Parser<'a> {
    pub token: Token,
    pub prev_token: Token,
    pub token_iter: &'a mut dyn Iterator<Item = Token>,
    pub is_eof: bool,
    /* private fields */
}

The parser. Turns token iter into AST.

Fields

token: Token

The current token.

prev_token: Token

The previous token.

token_iter: &'a mut dyn Iterator<Item = Token>

The token iter.

is_eof: bool

Is token iter end.

Implementations

impl<'a> Parser<'a>

pub fn new(token_iter: &'a mut dyn Iterator<Item = Token>) -> Self

Constructs a new Parser with a token iter.

pub fn parse(&mut self) -> Result<Box<Block>, ParserError>

Parse token iter into AST (Box<Block>).
