Struct TotalReader 

pub struct TotalReader<'b> { /* private fields */ }

An already configured CSV reader working on a slice of bytes or on a memory map.

Configuration

To configure a TotalReader, if you need a custom delimiter for instance of if you want to tweak the size of the inner buffer. Check out the TotalReaderBuilder.

Implementations

impl<'b> TotalReader<'b>

pub fn from_bytes(bytes: &'b [u8]) -> Self

Create a new reader with default configuration using the provided byte slice.

pub fn byte_headers(&mut self) -> &ByteRecord

Returns whether this reader has been configured to interpret the first record as a header.

pub fn count_records(&mut self) -> u64

Count the total number of records.

pub fn split_record(&mut self) -> Option<&[u8]>

Attempt to split the next CSV record and return an optional reference to its byte slice.

Returns Ok(None) when the reader is fully consumed.

pub fn read_byte_record(&mut self, record: &mut ByteRecord) -> bool

Attempt to read the next CSV record into a pre-allocated ByteRecord.

Returns a boolean indicating whether a record was actually read or if we reached the end of the stream.

pub fn byte_records<'r>(&'r mut self) -> ByteRecordsIter<'r, 'b>

Return an iterator yielding ByteRecord structs.

pub fn position(&self) -> u64

Returns the current byte offset of the reader into its byte slice.
