Enum rust_decimal::Error

pub enum Error {
    ErrorString(String),

Error type for the library.

Variants

ErrorString(String)

A generic error from Rust Decimal with the String containing more information as to what went wrong.

This is a legacy/deprecated error type retained for backwards compatibility.

ExceedsMaximumPossibleValue

The value provided exceeds Decimal::MAX.

LessThanMinimumPossibleValue

The value provided is less than Decimal::MIN.

Underflow

An underflow is when there are more fractional digits than can be represented within Decimal.

ScaleExceedsMaximumPrecision(u32)

The scale provided exceeds the maximum scale that Decimal can represent.

ConversionTo(String)

Represents a failure to convert to/from Decimal to the specified type. This is typically due to type constraints (e.g. Decimal::MAX cannot be converted into i32).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl<S> From<S> for Errorwhere S: Into<String>,

fn from(from: S) -> Self

Converts to this type from the input type.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> 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.
