0.6.2 compilation fails
Closed this issue · 3 comments
Hello and thanks for your library!
On compilation I get the following error which is mostly self-explanatory:
error[E0658]: use of unstable library feature 'shrink_to': new API
--> bimap-0.6.2/src/hash.rs:335:25
|
335 | self.left2right.shrink_to(min_capacity);
| ^^^^^^^^^

= note: see issue #56431 rust-lang/rust#56431 for more information
Oh, I didn't realize until now that HashMap::shrink_to was only added in Rust 1.56. Are you able to update your Rust install? The current stable release is 1.58.1.
Yes, that's what I did and it works fine, but I thought you might want to know as in some environments it might not be easy to update (due to ACL restrictions for example etc.). Or maybe you could indicate somewhere that the latest rust version is required for 0.6.2? (1.56 is dated late October 2021 which is quite recent). It's not a major problem anyways, thanks for your reply 😃
I will at least add some information to the README about the minimum supported Rust version. Thank you for pointing it out.
