Struct InputStream

pub struct InputStream<'t, I: Iterator<Item = &'t Token> + Clone> { /* private fields */ }

The stream (peekable iterator) of input tokens

Implementations

impl<'t, I: Iterator<Item = &'t Token> + Clone> InputStream<'t, I>

pub fn new<It: IntoIterator<IntoIter = I>>(it: It) -> Self

Create a new stream from an iterator over tokens.

pub fn parse<P: Parse>(&mut self) -> Result<P, Error>

Parse tokens as a node.

Errors

Returns an error if failed to parse

pub fn get_token(&mut self) -> Result<&'t Token, Error>

Get the next token

Errors

Returns an EOF error if there is no next token.

pub fn expect_token(&mut self) -> Result<(), Error>

Expect there to be a token. Does not advance the stream.

Errors

Returns an EOF error if there is no next token.

pub fn eof(&mut self) -> bool

Check if this is the end of input.
