Enum fixed_decimal::FixedDecimalError

#[non_exhaustive]
pub enum FixedDecimalError {
    Limit,
    Syntax,
}

An error involving FixedDecimal operations or conversion.

Variants (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.

Trait Implementations

impl Clone for FixedDecimalError

fn clone(&self) -> FixedDecimalError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FixedDecimalError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FixedDecimalError

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl PartialEq for FixedDecimalError

fn eq(&self, other: &FixedDecimalError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
