Enum DecimalConvertError 

pub enum DecimalConvertError {
    Overflow,
    NotFinite,
}

Error returned by the fallible TryFrom impls on I128.

Covers the two distinct failure modes:

• DecimalConvertError::Overflow – the input, after scaling by 10^SCALE, exceeds the range [I128::MIN, I128::MAX].
• DecimalConvertError::NotFinite – the float input is NaN, +inf, or -inf.

Variants

Overflow

Input magnitude is outside [I128::MIN, I128::MAX] after scaling.

NotFinite

Input is NaN, +inf, or -inf (only reachable from the TryFrom<f32> / TryFrom<f64> impls).

Trait Implementations

impl Clone for DecimalConvertError

fn clone(&self) -> DecimalConvertError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecimalConvertError

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

Formats the value using the given formatter.

impl Display for DecimalConvertError

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

Formats the error as a short human-readable message.

Precision

Strict: all arithmetic is integer-only; result is bit-exact.

impl Error for DecimalConvertError

Available on crate feature std only.

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 Hash for DecimalConvertError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DecimalConvertError

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