Expand description

Trait for parsers that can be used in a pull-based manner.

This trait is implemented by both SliceParser and StreamParser.

Required Methods§

Source

fn next_event(&mut self) -> Result<Event<'_, '_>, ParseError>

Returns the next JSON event or an error if parsing fails. Parsing continues until EndDocument is returned or an error occurs.

Provided Methods§

Source

fn next(&mut self) -> Option<Result<Event<'_, '_>, ParseError>>

Iterator-like method that returns None when parsing is complete. This method returns None when EndDocument is reached, Some(Ok(event)) for successful events, and Some(Err(error)) for parsing errors.
