The first commit breaks the 1200-line
deriving.rs
into multiple submodules, one for each derivable trait. I haven't made any effort yet to clean that code up, however.The second commit introduces
#[deriving(TotalOrd)]
, which creates an implementation based on the successive comparison of all struct/enum fields in their declaration order. A future patch will allow this to be configured in the attribute.
