@nastevens, thanks for reporting! 👍

@hmvp any idea what might have cause this to break? RawVec has been in use in libarena for a while. 🤔

[mbudde]

I guess it's this: rust-lang/rust@1acbb0a935 (rust-lang/rust#51569)

[hmvp]

Fixed with #22

[jan-hudec]

Please be so kind and release the bugfix too (to crates.io).

[regexident]

@jan-hudec, @nastevens I just pushed v0.4.2 to crates.io.
Sorry for taking so long. I simply forgot. 😇

[jan-hudec]

@regexident, thanks.

Unfortunately the GitHub issue tracker does not have any support for keeping track of which issues are fixed in master, but not released, so it is kind of easy to forget.
