Struct num_format::CustomFormat

pub struct CustomFormat { /* fields omitted */ }

Type for representing your own custom formats. Implements Format.

Example

use num_format::{Buffer, Error, CustomFormat, Grouping};

fn main() -> Result<(), Error> {
    let format = CustomFormat::builder()
        .grouping(Grouping::Indian)
        .minus_sign("🙌")
        .separator("😀")
        .build()?;

    let mut buf = Buffer::new();
    buf.write_formatted(&(-1000000), &format);
    assert_eq!("🙌10😀00😀000", buf.as_str());

    Ok(())
}
