Struct ra_ap_tt::TokenId

pub struct TokenId(pub u32);

Represents identity of the token.

For hygiene purposes, we need to track which expanded tokens originated from which source tokens. We do it by assigning an distinct identity to each source token and making sure that identities are preserved during macro expansion.
