Struct scale_info::prelude::num::ParseFloatError

pub struct ParseFloatError { /* private fields */ }

An error which can be returned when parsing a float.

This error is used as the error type for the FromStr implementation for f32 and f64.

Example

use std::str::FromStr;

if let Err(e) = f64::from_str("a.12") {
    println!("Failed conversion to f64: {e}");
}

Trait Implementations

impl Clone for ParseFloatError

fn clone(&self) -> ParseFloatError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseFloatError

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

Formats the value using the given formatter.

impl Display for ParseFloatError

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

Formats the value using the given formatter.

impl Error for ParseFloatError

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl PartialEq<ParseFloatError> for ParseFloatError

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