pub struct Lexer<'a> { /* private fields */ }

The lexer. It gives one token for each call of Lexer::next_token.

Implementations

impl<'a> Lexer<'a>

pub fn new(text: &'a str) -> Lexer<'a>

A lexer for text. The text ends at the first zero byte, as the C string that PostgreSQL gets does.

pub fn text(&self) -> &'a str

The text that the lexer reads.

pub fn take_notices(&mut self) -> Vec<Notice>

Takes the notices that the tokens until now gave.

pub fn next_token(&mut self) -> Result<Token<'a>, Error>

The next token. After the last token it gives the end, token 0, again and again.

Trait Implementations

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