Please support FreeBSD

There's no freebsd.rs

The Reth project can't be compiled on FreeBSD because of this problem. https://github.com/paradigmxyz/reth/issues/5918

I know little to nothing about freebsd or how to get the metrics values on that OS:

https://github.com/lambdalisue/rs-metrics-process/blob/dbb1d752e0b497d32853a6c7b3acd77d6f64157d/src/collector/linux.rs#L10

maybe via https://github.com/johalun/sysctl-rs and/or https://github.com/fubarnetes/rctl

but perhaps there can be collect that returns an empty Metrics for freebsd so that it at least compiles on freebsd?

[lambdalisue]

I've no idea about FreeBSD so I cannot implement it by myself. PR is welcome.

Not sure if that should be applied on this crate. I think user (in this case, reth?) should remove this crate with #cfg() instead.

[lambdalisue]

Maybe we can add dummy feature that add a dummy collector that is used for non supported platform?

[mattsse]

that would be very useful imo, just so that it compiles

[lambdalisue]

A dummy feature is added. Please close the issue if that is what you needed actually or keep open it if you really need FreeBSD support @yurivict
