> Currently `MutableBuffer#resize` adjust the buffer's capacity. This is
> slightly confusing, and is not conforming with Rust's as
> [vector|https://doc.rust-lang.org/std/vec/struct.Vec.html#method.resize], as
> well as C++'s buffer impl.
> This proposes to rename the `resize` to `reserve`, and modify the current
> `set_len` to `resize`. We'll also allow `resize` to shrink the buffer so as
> to free up unnecessary space.
