Trait ParserInput

pub trait ParserInput: Clone + Iterator<Item = TokenAndSpan> {
    type State: Debug;

    // Required methods
    fn start_pos(&mut self) -> BytePos;
    fn state(&mut self) -> Self::State;
    fn reset(&mut self, state: &Self::State);
    fn take_errors(&mut self) -> Vec<Error>;

}

Required Associated Types

type State: Debug

Required Methods

fn start_pos(&mut self) -> BytePos

fn state(&mut self) -> Self::State

fn reset(&mut self, state: &Self::State)

fn take_errors(&mut self) -> Vec<Error>

fn skip_ws(&mut self) -> Option<BytePos>

Returns last_pos

fn atom(&self, s: Cow<'_, str>) -> Atom

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
