Implementations§

Source§

impl<R: Read> NdjsonReader<R>

Source

pub fn new(reader: BufReader<R>) -> Self

Source§

impl<R: Read + Seek + Send> NdjsonReader<R>

Source

pub fn reset_seekable(&mut self) -> Result<()>

Trait Implementations§

Source§

impl<R: Read + Send> SourceReader for NdjsonReader<R>

Source§

fn next_row(&mut self) -> Result<Option<SourceRow>>

Source§

fn headers(&self) -> &[String]

Source§

fn supports_reset(&self) -> bool

Whether reset() is actually supported by this reader. Readers wrapping non-seekable streams (stdin, network) return false.
Source§

fn reset(&mut self) -> Result<()>

Attempt to reset the reader to the beginning. Returns Ok(()) even if unsupported — check supports_reset() first.
