Struct InstallHost 

pub struct InstallHost {
    pub platform: Platform,
    pub manager: Option<PackageManager>,
    pub engines: Vec<EngineKind>,
}

The machine the guidance is written for.

Carried as data rather than read from cfg! where it is needed, so the guidance for all three operating systems is checked on one machine.

Fields

platform: Platform

Which system’s rules to follow.

manager: Option<PackageManager>

The program that installs software here, when QCode recognises one.

engines: Vec<EngineKind>

The engines already on this machine, Podman before Docker. It is what the wizard ticks when the settings file names no engine: offering to install what is already installed would be the wizard ignoring the machine it is standing on.

Implementations

impl InstallHost

pub fn detect() -> Self

Reads the machine this program runs on.

pub fn read( platform: Platform, release: Option<&str>, installed: impl Fn(&str) -> bool, ) -> Self

The host platform describes, with release the text of the Linux os-release file and installed answering whether a program is on the person’s PATH.

Both are parameters so a test can describe any distribution from any machine.
