Struct rug::rational::TryFromFloatError

pub struct TryFromFloatError { /* private fields */ }

An error which can be returned when a checked conversion from a floating-point number to a Rational number fails.

Examples

use rug::rational::TryFromFloatError;
use rug::Rational;
// This is not finite and cannot be converted to Rational.
let inf = 1.0f32 / 0.0;
let error: TryFromFloatError = match Rational::try_from(inf) {
    Ok(_) => unreachable!(),
    Err(error) => error,
};
println!("Error: {}", error);

Trait Implementations

impl Clone for TryFromFloatError

fn clone(&self) -> TryFromFloatError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TryFromFloatError

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

Formats the value using the given formatter.

impl Display for TryFromFloatError

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

Formats the value using the given formatter.

impl Error for TryFromFloatError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

The lower-level source of this error, if any.

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 TryFromFloatError

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