Struct CsvRecordReader

Source

pub struct CsvRecordReader<R> { /* private fields */ }

Expand description

Reads records one at a time. Each record is bounded by CsvImportLimits::max_record_bytes and CsvImportLimits::max_fields_per_record, and the whole input by CsvImportLimits::max_file_bytes.

Implementations§

Source §

impl<R: Read> CsvRecordReader<R>

Source

pub fn new(input: R, terminator: u8, limits: CsvImportLimits) -> Result<Self>

Source

pub fn records(&self) -> u64

Records returned so far, including a header record.

Source

pub fn next_record(&mut self) -> Result<Option<Vec<CsvField>>>

Returns the next record, skipping lines that contain no bytes at all.
