Enum fixed_decimal::FixedDecimalError

source ·
#[non_exhaustive]
pub enum FixedDecimalError { Limit, Syntax, }
Expand description

An error involving FixedDecimal operations or conversion.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Limit

The magnitude or number of digits exceeds the limit of the FixedDecimal. The highest magnitude of the most significant digit is i16::MAX, and the lowest magnitude of the least significant digit is i16::MIN.

This error is also returned when constructing a FixedInteger from a FixedDecimal with a fractional part.

§Examples

use fixed_decimal::Error;
use fixed_decimal::FixedDecimal;

let mut dec1 = FixedDecimal::from(123);
dec1.multiply_pow10(i16::MAX);
assert!(dec1.is_zero());
§

Syntax

The input of a string that is supposed to be converted to FixedDecimal is not accepted.

Any string with non-digit characters (except for one ‘.’ and one ‘-’ at the beginning of the string) is not accepted. Also, empty string (“”) and its negation (“-”) are not accepted. Strings of form “12_345_678” are not accepted, the accepted format is “12345678”. Also ‘.’ shouldn’t be first or the last characters, i. e. .123 and 123. are not accepted, and instead 0.123 and 123 (or 123.0) must be used.
