Struct csv_core::WriterBuilder

pub struct WriterBuilder { /* fields omitted */ }

A builder for configuring a CSV writer.

This builder permits specifying the CSV delimiter, terminator, quoting style and more.

Methods

impl WriterBuilder

fn new() -> WriterBuilder

Create a new builder for configuring a CSV writer.

fn build(&self) -> Writer

Builder a CSV writer from this configuration.

fn delimiter(&mut self, delimiter: u8) -> &mut WriterBuilder

The field delimiter to use when writing CSV.

The default is b','.

fn terminator(&mut self, term: Terminator) -> &mut WriterBuilder

The record terminator to use when writing CSV.

A record terminator can be any single byte. The default is \n.

Note that RFC 4180 specifies that record terminators should be \r\n. To use \r\n, use the special Terminator::CRLF value.

fn quote_style(&mut self, style: QuoteStyle) -> &mut WriterBuilder

The quoting style to use when writing CSV.

By default, this is set to QuoteStyle::Necessary, which will only use quotes when they are necessary to preserve the integrity of data.

Note that unless the quote style is set to Never, an empty field is quoted if it is the only field in a record.

fn quote(&mut self, quote: u8) -> &mut WriterBuilder

The quote character to use when writing CSV.

The default value is b'"'.

fn escape(&mut self, escape: u8) -> &mut WriterBuilder

The escape character to use when writing CSV.

This is only used when double_quote is set to false.

The default value is b'\\'.

fn double_quote(&mut self, yes: bool) -> &mut WriterBuilder

The quoting escape mechanism to use when writing CSV.

When enabled (which is the default), quotes are escaped by doubling them. e.g., " escapes to "".

When disabled, quotes are escaped with the escape character (which is \\ by default).
