Struct Selection 

pub struct Selection {
    pub distro: Option<Distro>,
    pub triple: Option<String>,
    pub glibc: Option<GlibcVersion>,
    pub kernel: Option<KernelVersion>,
}

A validated selection.

Fields

distro: Option<Distro>

The preset, when one was chosen.

triple: Option<String>

Rust target triple without any glibc suffix, when one was given.

glibc: Option<GlibcVersion>

glibc floor; None means the host’s glibc.

kernel: Option<KernelVersion>

Kernel floor; None means the kernel is not simulated (host kernel).

Implementations

impl Selection

pub fn resolve(req: &Request<'_>) -> Result<Self, String>

Applies the selection rules:

• distro excludes glibc, kernel, and a versioned target.
• A versioned target (TRIPLE.X.Y) sets the glibc floor; it must agree with glibc if both are given. It never implies a kernel.
• Anything not given stays None: host glibc, host kernel.

pub fn image(&self) -> Option<&'static str>

The container image for runtime tests, if the selection has one.

pub fn describe(&self) -> String

A one-line description for tool output, e.g. glibc 2.22, kernel 4.12 (SUSE Linux Enterprise Server 12 SP5) or glibc host, kernel not simulated (host).

Trait Implementations
