Enum PrecisionError 

pub enum PrecisionError {
    InvalidStep(Decimal),
    StepsOverflow {
        value: Decimal,
        step: Decimal,
    },
}

Why a step calculation was refused.

Examples

use brokapi_bcs_protocol::utils::precision::{precise_down, PrecisionError};
use rust_decimal::Decimal;

assert!(matches!(
    precise_down(Decimal::ONE_HUNDRED, Decimal::ZERO),
    Err(PrecisionError::InvalidStep(_))
));

Variants

InvalidStep(Decimal)

The step is zero or negative.

StepsOverflow

The count of steps does not fit in an i64, or a number overflowed.

Fields

value: Decimal

The value that was converted.

step: Decimal

The step it was divided by.

Trait Implementations

impl Clone for PrecisionError

fn clone(&self) -> PrecisionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrecisionError

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

Formats the value using the given formatter.

impl Display for PrecisionError

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

Formats the value using the given formatter.

impl Eq for PrecisionError

impl Error for PrecisionError

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 PrecisionError

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