smallvec macro in no_std code

[debris]

hey! I'm trying to use smallvec! macro in no_std library. Is it possible?

code:

smallvec![a];

fails with:

error: cannot find macro `vec` in this scope
  --> example.rs:2:1
   |
2  | smallvec![a]

I already imported extern crate alloc

I haven't actually done this so forgive me if it's not on the right track: It looks like you need to macro_use extern crate std, since that's where vec! is defined.

@debris According to https://stackoverflow.com/questions/51516773/how-to-use-vec-macro-in-a-no-std-library you need to add a #[macro_use] to your extern crate alloc.
