Specify MSRV

[kemingy]

• replace once_cell::sync::Lock with std::sync::LazyLock
• remove some useless ;
• mark some functions as const
• add MSRV

Thank you very much for the PR. Someone else created an almost identical PR #1681 which I saw first. So this PR now boils down to the MSRV. The version you have set seems to be pretty high. Is this the lowest version the project still compiles?

The msrv is generated by https://github.com/foresterre/cargo-msrv

You can verify with this tool.

Awesome, I didn't know about the tool. I also got 1.83.0.
Could you update the PR to just include the MSRV?

Looks good. Thank you!

Nice. @kemingy, maybe you'd like to create a follow-up pull request to verify that the MSRV is correct in CI? Basically call
https://gribnau.dev/cargo-msrv/commands/verify.html in https://github.com/lycheeverse/lychee/blob/master/.github/workflows/ci.yml (or perhaps in a separate pipeline that runs regularly; up to you.
