Struct std::num::ParseIntError1.0.0[][src]

pub struct ParseIntError { /* fields omitted */ }

An error which can be returned when parsing an integer.

This error is used as the error type for the from_str_radix() functions on the primitive integer types, such as i8::from_str_radix.

Potential causes

Among other causes, ParseIntError can be thrown because of leading or trailing whitespace in the string e.g., when it is obtained from the standard input. Using the str::trim() method ensures that no whitespace remains before parsing.


if let Err(e) = i32::from_str_radix("a12", 10) {
    println!("Failed conversion to i32: {}", e);

pub fn kind(&self) -> &IntErrorKind[src]

🔬 This is a nightly-only experimental API. (int_error_matching #22639)

it can be useful to match errors when making error messages for integer parsing

Outputs the detailed cause of parsing an integer failing.
