Struct core::num::ParseFloatError

1.0.0 · 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}");
}
