Struct core::num::ParseIntError  
1.0.0 · source · [−]pub struct ParseIntError { /* private fields */ }Expand description
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.
Example
if let Err(e) = i32::from_str_radix("a12", 10) {
    println!("Failed conversion to i32: {}", e);
