Struct CsvWriter 

pub struct CsvWriter { /* private fields */ }

CSV writer that builds the output in memory.

A typical admin export fits in memory. For very large ones, write in batches and flush each batch yourself.

Implementations

impl CsvWriter

pub fn new() -> Self

New empty writer.

pub fn headers<I, S>(&mut self, headers: I)

where I: IntoIterator<Item = S>, S: AsRef<str>,

Write the header row. This fixes the column count: later rows are padded or truncated to match.

pub fn row<I, S>(&mut self, row: I)

where I: IntoIterator<Item = S>, S: AsRef<str>,

Write a data row. After headers(), the row is padded with empty strings or cut down to the column count.

pub fn into_string(self) -> String

Take the buffered output.

pub fn as_str(&self) -> &str

Look at the buffered output so far.

pub fn raw_formulas(self) -> Self

Write values byte for byte, skipping formula neutralisation.

Use this only for CSV read by a machine. If a person may open the file in Excel, LibreOffice or Sheets, keep the default: see neutralize_formula.

Trait Implementations
