Struct Facts 

pub struct Facts<'a> {
    pub machine: Machine<'a>,
    pub present: &'a dyn Fn(&str) -> bool,
    pub free_bytes: &'a dyn Fn(&Path) -> Option<u64>,
    pub gpus: &'a dyn Fn() -> Vec<String>,
    pub repositories: &'a dyn Fn() -> Option<Vec<String>>,
    pub sizes: &'a dyn Fn(PackageManager, &[String]) -> Option<u64>,
    pub active_runs: &'a dyn Fn() -> Vec<String>,
}

What the checks ask the machine; tests answer instead.

Fields

machine: Machine<'a>

Package questions, as planning asks them.

present: &'a dyn Fn(&str) -> bool

Whether a command, or an absolute path, is present.

free_bytes: &'a dyn Fn(&Path) -> Option<u64>

Free bytes on the file system holding a path.

gpus: &'a dyn Fn() -> Vec<String>

The graphics vendors found (nvidia, amd, intel).

repositories: &'a dyn Fn() -> Option<Vec<String>>

The enabled pacman repositories; None off Arch or when unreadable.

sizes: &'a dyn Fn(PackageManager, &[String]) -> Option<u64>

The installed size in bytes of packages not yet installed, when the package manager can say.

active_runs: &'a dyn Fn() -> Vec<String>

Other HelixForge runs still going, by their entries’ names.
