Struct std::num::ParseIntError

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.

Implementations

`impl ParseIntError`[src]

`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.
