Enum std::string::ParseError

[+] Show type declaration

pub enum ParseError {}

[−] Expand description

An error when parsing a String.

This enum is slightly awkward: it will never actually exist. This error is part of the type signature of the implementation of FromStr on String. The return type of from_str, requires that an error be defined, but, given that a String can always be made into a new String without error, this type will never actually be returned. As such, it is only here to satisfy said signature, and is useless otherwise.
