Crate linux_targets 

Linux target selection shared by the rustcommons toolchain.

A target is chosen in one of two ways:

• A distribution preset (--distro sles-12-sp5): supplies the glibc floor, the kernel floor, and a container image with the real userland.
• Explicit floors (--glibc 2.22, --kernel 4.12, or a versioned target such as x86_64-unknown-linux-gnu.2.22): each is optional. A missing kernel floor means the kernel is not simulated: programs run against the host kernel.

A preset cannot be combined with explicit floors: “SLES 12 SP5 with glibc 2.28” is not a real system. Selection::resolve enforces these rules.

Structs

Distro

A distribution preset: a kernel floor, a glibc floor, and a test image.

Release

A major.minor release number, such as a kernel (4.12) or glibc (2.22) release. Comparison uses only these two components.

Request

What the user selected, before validation.

Selection

A validated selection.

Functions

distro

The preset with this id.

distros

All distribution presets from data/distros.tsv.

split_versioned_target

Splits x86_64-unknown-linux-gnu.2.17 into the Rust triple and the glibc floor. A triple without a numeric .X.Y suffix is returned unchanged.

Type Aliases

GlibcVersion

A GNU C Library release.

KernelVersion

A mainline Linux kernel release.
