Parses the string buf as unsigned representation in the specified base
of an integral value of type T.
When base is zero the string prefix is examined to detect the true base:
Ignores '_' character in buf.
See also parseInt.
pub fn parseUnsigned(comptime T: type, buf: []const u8, base: u8) ParseIntError!T
pub fn parseUnsigned(comptime T: type, buf: []const u8, base: u8) ParseIntError!T {
return parseIntWithSign(T, u8, buf, base, .pos);
