smallvec dependency is outdated #117
Description
I am working on enabling rustc to find misuses of uninitialized memory (rust-lang/rust#71274), and one crate that indirectly depends on this one came up as a regression in crater. I do not know what the exact cause of the regression is, but I did notice that this crate depends on an ancient version of smallvec, 0.6.1. Smallvec has seen a 1.0 release since then, it would be great if this crate could bump its dependency and use the latest version. :)
