pub struct CsvRowReader<R> { /* private fields */ }Available on crate feature
file-format-csv only.Expand description
A streaming CSV reader yielding one JSON object per row.
Header names must be unique: rows are keyed by header, so a repeated name would silently drop a column. A ragged row fails naming its line unless the dialect is flexible.

pub fn new( reader: R, opts: &CsvOptions, default_flexible: bool, ) -> Result<Self, FaucetError>
Build a reader over reader with the dialect in opts.
Sourcepub async fn next_record(&mut self) -> Result<Option<Value>, FaucetError>
pub async fn next_record(&mut self) -> Result<Option<Value>, FaucetError>
The next row, or None at the end of the input.
