Enum FloatErrorKind 

#[non_exhaustive]
pub enum FloatErrorKind {
    Empty,
    Invalid,
}

🔬This is a nightly-only experimental API. (extended_float_error_kind #164793)

An error kind which can be returned when parsing a float.

This error kind is used as the inner error type in ParseFloatError for the FromStr implementation for f32 and f64.

Example

#![feature(extended_float_error_kind)]

use std::str::FromStr;

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

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

🔬This is a nightly-only experimental API. (extended_float_error_kind #164793)

Cannot parse float from empty string.

Invalid

🔬This is a nightly-only experimental API. (extended_float_error_kind #164793)

Invalid float literal.
