"pure safe crates"

• totally-safe-transmute

  17 245 0.0 Rust

I'm not sure this would be super useful. Many crates with no unsafe have dependencies which do rely on unsafe code. And, even without unsafe, you can engage in serious shenanigans. Just gonna drop this here... ;-)

• tinyvec

  4 605 4.4 Rust

  Just, really the littlest Vec you could need. So smol.

I've seen the cost of zeroing memory be measurable, or maybe significant enough to care about, but I've never seen 90% of cycles spent on it, the only case I know of that gets close is creating an empty TinyVec versus an empty SmallVec with an inline buffer of 256 bytes. In my opinion that's an unreasonably large inline buffer. At inline buffers of 128 bytes and below, the overhead is less than 50%, and that's on a microbenchmark of the Default impl; the effect is rapidly diluted in a real program.

• serde

  191 8,606 9.1 Rust

  Serialization framework for Rust

  

Alternatively, I can point to this serde PR where creatively initializing a buffer is faster or indistinguishable in performance from not initializing it.
