Module matrix 

Feature matrix generation for cargo xtask test and cargo xtask clippy.

Scans every Cargo.toml in the workspace, collects the union of all non-default feature names, and produces every power-set combination crossed with a list of target operating systems. Each combination becomes one MatrixEntry that maps to a single CI job.

The same entries are used locally (by test and clippy tasks) and in CI (by cargo xtask ci matrix, which serialises them to GitHub Actions JSON).

Structs

MatrixEntry

One entry in the feature × OS matrix.

Constants

CI_CLIPPY_OS

Operating systems included in the CI clippy matrix.

Functions
