according to this: https://docs.rs/crate/rustc-ap-arena/491.0.0/source/lib.rs , self.storage is alloc::raw_vec::RawVec<T>. and from https://github.com/rust-lang/rust/blob/4268e7ee22935f086b856ef0063a9e22b49aeddb/src/liballoc/raw_vec.rs#L204 it might be renamed to capacity() from cap().

@jiacai2050 @koka831 Thank you for reporting and sorry for the delay in response. I'm going to fix it

3. build locally `cargo +nightly build --release`

As I'm new to rust I'm not confident enough to submit it as PR, but hopefully it will help in the meantime.
kngwyu commented 5 years ago

@mathewcohle Thanks, looks ExprKind::IfLet has gone...

mathewcohle commented 5 years ago

@kngwyu indeed, see https://github.com/rust-lang/rust/pull/60861

davesque commented 5 years ago

After applying that patch (or trying the fix branch from the PR), I'm still getting build errors:
