Support for lifetimes

[magnusart]

When I try to add a lifetime generic I get a compiler error:

bty::brand!(
    pub type UserName = &'static str; // This works!
    pub type UserEmail<'a> = &'a str; // Error: no rules expected the token `<`
    // no rules expected this token in macro call
);

Suggestion: provide support for lifetime parameters.

Note! I'm new to rust so forgive me if this is a newbie mistake regarding the lifetime.

Yeah, that's indeed not currently supported, as the macro definition only accepts an identifier token, see:

bty/src/lib.rs

Line 42 in 48f7786

$vis:vis type $tag:ident = $raw:ty ;

I shall commit a patch that fixes the syntax to allow lifetimes, generic parameter and trait bounds as soon as possible. Thanks for the report. :)
