Struct std::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);
