2013-11-19Mark some derived methods as #[inline].Huon Wilson-0/+4
ToStr, Encodable and Decodable are not marked as such, since they're already expensive, and lead to large methods, so inlining will bloat the metadata & the binaries. This means that something like #[deriving(Eq)] struct A { x: int } creates an instance like #[doc = "Automatically derived."] impl ::std::cmp::Eq for A { #[inline] fn eq(&self, __arg_0: &A) -> ::bool { match *__arg_0 { A{x: ref __self_1_0} => match *self { A{x: ref __self_0_0} => true && __self_0_0.eq(__self_1_0) } } } #[inline] fn ne(&self, __arg_0: &A) -> ::bool { match *__arg_0 { A{x: ref __self_1_0} => match *self { A{x: ref __self_0_0} => false || __self_0_0.ne(__self_1_0) } } } } (The change being the `#[inline]` attributes.)
2013-10-02std: Swap {To,From}Primitive to use the 64bit as the unimplemented versionErick Tryzelaar-6/+6
One downside with this current implementation is that since BigInt's default is now 64 bit, we can convert larger BigInt's to a primitive, however the current implementation on 32 bit architectures does not take advantage of this fact.
2013-10-02syntax: swap from .span_fatal to .span_err in #[deriving(FromPrimitive)]Erick Tryzelaar-7/+14
2013-10-02syntax: Add #[deriving(FromPrimitive)] syntax extensionErick Tryzelaar-0/+120
Right now this only works for c-style enums.
