use std::fs::File;
fn example() -> csv::Writer<File> {
let file = File::create("target/out.csv").unwrap();
// create a builder that doesn't write headers
let builder = csv::WriterBuilder::new().has_headers(false);
let writer = builder.build(file);
writer
}
sourcepub fn has_headers(self, has_headers: bool) -> Self
pub fn has_headers(self, has_headers: bool) -> Self
Set whether to write headers
sourcepub fn with_delimiter(self, delimiter: u8) -> Self
pub fn with_delimiter(self, delimiter: u8) -> Self
