fix build.rs

[freeferg]

build.rs was causing the a crash during the installation with cargo :

error[E0432]: unresolved import std::fs::exists --> imessage-database/build.rs:3:16 | 3 | fs::{copy, exists}, | ^^^^^^ no exists i

On what platform and cargo version does this crash? I am able to install and run imessage-exporter on Windows and MacOS via cargo 1.81.0 (2dbb1af80 2024-08-20) without this issue. The import definitely exists as well:

• https://doc.rust-lang.org/nightly/std/fs/fn.exists.html
• https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=fb050e0e75559ac265cf5c32081cde15

It crashes on MacOS Sequioa 15.0 with cargo 1.80.0.

I am unable to replicate this issue using the same platform and cargo version. Can you post the full compiler error?

The import is definitely valid, as you can see from this playground.

Closing this pull request.

Upon review, the issue this PR claims to address does not appear to actually exist in imessage-exporter.

If you believe this is in error, please provide additional context or explain the specific issue this PR is meant to address. Otherwise, feel free to open a new PR/issue if you've identified a legitimate problem that needs solving.

Thank you for your contribution.

Hello! I'm getting the same issue on Arch Linux 6.11.3 with cargo version 1.78.0. Here is my compilation output:

Use a newer version of Rust: https://doc.rust-lang.org/src/std/fs.rs.html#2752

Ah I was not aware that rustup needed to be updated outside of pacman, thank you!
