Documentation for x86_64-unknown-linux-gnu is missing from `docs.rs`

[proski]

The current documentation on docs.rs is missing the x86_64-unknown-linux-gnu platform: https://docs.rs/socket2/0.5.8/socket2/

The documentation build logs can be seen at https://docs.rs/crate/socket2/0.5.8/builds

Key takeaways:

A new documentation build was run on 2025-02-22. An older build for the same version 0.5.8 was run on 2024-11-27.

Both builds include 11 platforms. Cargo.toml lists 14 platforms as targets for documentation. The most recent build is missing x86_64-unknown-linux-gnu, the older build has that platform but is missing other platforms.

I don't see any information that docs.rs is limited to 11 platforms. But there is a very old mention that it's limited to 10 platforms: rust-windowing/winit#1028 (comment)

The docs.rs build status page https://docs.rs/crate/socket2/0.5.8/builds is showing at the end:

Maximum number of build targets | 10
If a build fails because it hit one of those limits please open an issue to get them increased.

I assume the are 11 targets because the default target is exempt from the limit.

I guess a ticket to increase the number of build targets needs to be opened by following the link of that page.

Perhaps some targets could be removed from Cargo.toml. For instance, x86_64-unknown-linux-musl only differs from other targets by internal implementation details in the private into_timeval function and in the private IovLen type.
