Struct syntax_rs::parse::ParseStream

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

Implementations

impl<'a> ParseStream<'a>

pub fn new(slice: &'a [char]) -> ParseStream<'a>

pub fn empty() -> ParseStream<'a>

pub fn snapshot(&self) -> Snapshot

pub fn since(&self, snapshot: Snapshot) -> Span

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

pub fn exhaustive_parse<P: Parse>(&mut self) -> Result<Vec<P>>

Parse until the cursor is empty or there are only whitespaces left.

pub fn cur(&mut self) -> &mut Cursor<'a>

pub fn is_empty(&self) -> bool

pub fn is_only_whitespaces(&self) -> bool

pub fn skip_all(&mut self, pred: impl FnMut(char) -> bool) -> bool

pub fn try_parse<R>(
    &mut self,
    parse_fn: impl FnOnce(&mut ParseStream<'a>) -> Result<R>
) -> Result<R>

Tries to parse something using the parse_fn parameter. On failure; the cursor is reset to it’s original value.
NOTE: This function is generally much more expensive than just doing a simple check before parsing.
