Struct ParseFloatError

1.6.0 · Source
pub struct ParseFloatError { /* private fields */ }
Expand description

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<C, E> EntryToVal<C> for E
where C: Collection<Entry = E>,

Source§

type Val = <C as Collection>::Val
