Enum AmountError 

pub enum AmountError {
    ScaleTooLarge,
    ScaleMismatch {
        left: u8,
        right: u8,
    },
    Overflow,
    PrecisionLoss,
}

Errors returned by amount helpers.

Variants

ScaleTooLarge

Decimal scales above 18 are intentionally unsupported.

ScaleMismatch

Arithmetic requires matching scales.

Fields

left: u8

Left-hand amount scale.

right: u8

Right-hand amount scale.

Overflow

Integer arithmetic overflowed.

PrecisionLoss

Rescaling would discard non-zero minor units.

Trait Implementations

impl Clone for AmountError

fn clone(&self) -> AmountError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AmountError

impl Debug for AmountError

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

Formats the value using the given formatter.

impl Display for AmountError

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

Formats the value using the given formatter.

impl Eq for AmountError

impl Error for AmountError

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

Returns 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 AmountError

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

Tests for self and other values to be equal, and is used by ==.

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

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