Struct Writer 

pub struct Writer<W: Write> { /* private fields */ }

An already configured CSV writer.

Configuration

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

Implementations

impl<W: Write> Writer<W>

pub fn from_writer(writer: W) -> Self

Create a new writer with default configuration using the provided writer implementing std::io::Write.

Avoid providing a buffered writer because buffering will be handled for you by the Writer.

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

Flush the underlying BufWriter.

pub fn write_record_no_quoting<I, T>(&mut self, record: I) -> Result<()>

where I: IntoIterator<Item = T>, T: AsRef<[u8]>,

Write the given “record” while foregoing any quoting/escaping.

This method accepts any item implementing IntoIterator and yielding references to byte slices.

BEWARE: if written data needed escaping, invalid CSV will be written!

Only use this method when you can guarantee you are doing the right thing and want the extra performance.

pub fn write_byte_record_no_quoting( &mut self, record: &ByteRecord, ) -> Result<()>

Write the given ByteRecord while foregoing any quoting/escaping.

BEWARE: if written data needed escaping, invalid CSV will be written!

Only use this method when you can guarantee you are doing the right thing and want the extra performance.

pub fn write_record<I, T>(&mut self, record: I) -> Result<()>

where I: IntoIterator<Item = T>, T: AsRef<[u8]>,

Write the given “record”.

This method accepts any item implementing IntoIterator and yielding references to byte slices.

pub fn write_byte_record(&mut self, record: &ByteRecord) -> Result<()>

Write the given ByteRecord.

pub fn write_splitted_record(&mut self, record: &[u8]) -> Result<()>

Write the given byte slice, as-is, without quoting/escaping, with an added newline.

BEWARE: if written data needed escaping, invalid CSV will be written!

This method can typically be used with slices yielded by Splitter.split_record.

pub fn into_inner(self) -> Result<W, IntoInnerError<BufWriter<W>>>

Attempt to unwrap the underlying BufWriter by flusing it and returning the original writer.
