Struct fixed_decimal::FixedInteger

source ·
pub struct FixedInteger(/* private fields */);
Expand description

A FixedInteger is a SignedFixedDecimal with no fractional part.

§Examples

use fixed_decimal::SignedFixedDecimal;
use fixed_decimal::FixedInteger;
use fixed_decimal::LimitError;

assert_eq!(
    SignedFixedDecimal::from(FixedInteger::from(5)),
    SignedFixedDecimal::from(5)
);
assert_eq!(
    FixedInteger::try_from(SignedFixedDecimal::from(5)),
    Ok(FixedInteger::from(5))
);
assert_eq!(
    FixedInteger::try_from(SignedFixedDecimal::from_str("05").unwrap()),
    Ok(FixedInteger::from_str("05").unwrap())
);
assert_eq!(
    FixedInteger::try_from(SignedFixedDecimal::from_str("5.0").unwrap()),
    Err(LimitError)
);
