Struct scale_info::prelude::num::ParseFloatError

pub struct ParseFloatError { /* fields omitted */ }

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);
}

impl Eq for ParseFloatError

impl Error for ParseFloatError

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

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

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<ParseFloatError> for ParseFloatError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
