Struct OverflowError 

pub struct OverflowError {
    pub currency: Currency,
}

A Decimal computation whose result cannot be represented.

rust_decimal is a 96-bit type with a hard ~±7.9e28 magnitude ceiling and its +/* panic on overflow. There is no in-range answer to substitute, so the arithmetic reports instead of clamping.

Used where an operation MUTATES an inventory, so a caller that reports and continues needs to know which currency was left alone. Pure leaf arithmetic returns a plain Option instead and lets its caller supply the context: crate::Cost::total_cost, sum_account_and_subaccounts, and rustledger_booking’s weight ladder. The split is about who is positioned to write the diagnostic, not about which failures matter.

Fields

currency: Currency

The currency whose running total left the range.

Trait Implementations

impl Clone for OverflowError

fn clone(&self) -> OverflowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OverflowError

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

Formats the value using the given formatter.

impl Display for OverflowError

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

Formats the value using the given formatter.

impl Eq for OverflowError

impl Error for OverflowError

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 From<OverflowError> for BookingError

fn from(e: OverflowError) -> Self

Converts to this type from the input type.

impl PartialEq for OverflowError

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

Equality operator ==.

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