Struct Reader

struct Reader<'a, 'ob> {
    tokens: Tokenizer<'a>,
    cx: &'ob Context<'ob>,
}

State of the reader.

Fields

tokens: Tokenizer<'a>

The iterator over the tokens in the current slice.

cx: &'ob Context<'ob>

New objects are allocated in the context.

Implementations

impl<'a, 'ob> Reader<'a, 'ob>

fn read_cdr( &mut self, delim: usize, ) -> Result<Option<Gc<ObjectType<'ob>>>, Error>

Read the cdr of a literal list.

'(1 2 3 . 45)
          ^^^

fn read_list(&mut self, delim: usize) -> Result<Gc<ObjectType<'ob>>, Error>

fn read_vec(&mut self, delim: usize) -> Result<Gc<ObjectType<'ob>>, Error>

fn quote_item( &mut self, pos: usize, symbol: Symbol<'_>, ) -> Result<Gc<ObjectType<'ob>>, Error>

Quote an item using symbol.

fn read_radix( &mut self, pos: usize, radix: u8, ) -> Result<Gc<ObjectType<'ob>>, Error>

Read number with specificed radix

fn read_sharp(&mut self, pos: usize) -> Result<Gc<ObjectType<'ob>>, Error>

read a sharp quoted character. This could be used for reader macro’s in the future, but right now it just handles the special cases from elisp.

fn read_sexp(&mut self, token: Token<'a>) -> Result<Gc<ObjectType<'ob>>, Error>
