Description

Feature gate: #![feature(is_ascii_octdigit)]

This is a tracking issue for two new methods char::is_ascii_octdigit and u8::is_ascii_octdigit, which, in the same vein as is_ascii_hexdigit, checks if a value is an ASCII octal digit ('0'..='7').

This is a shorthand for {char, u8}::is_digit(self, 8). Prior discussion on irlo.
