holger-recipe/Cargo.toml
# holger's **recipe** — the one Rust declaration of holger's build space.
#
# ## A PLAIN RLIB, and that is why this crate exists (MEASURED 2026-09-16)
#
# The declaration first lived directly in `holger-build-thing`, which must be a
# `cdylib` (dwarves' code road refuses a `<repo>-build-thing` that is not). For a
# lib whose `crate-type` contains `cdylib`, cargo emits NO `--extra-filename`, so
# every unit of it writes the same `target/debug/deps/libholger_build_thing.rlib`.
# build-space reaches it with a different feature resolution under its tests
# (its dev-deps turn on nornir-build-thing features) than its lib does, so there
# were two units and one filename, and the doctest linked the loser:
#
# error[E0460]: found possibly newer version of crate `holger_build_thing`
# which `holger_build_space` depends on
#
# green when run alone, red inside `cargo test -p holger-build-space
# --no-fail-fast` — the same cargo#6313 shape gunnar recorded 2026-09-03 and fixed
# with the same split: the recipe is a plain rlib (it gets an `--extra-filename`,
# so its units coexist) and `holger-build-thing` is a shim nothing depends on.

# graph), computed over holger's own manifests with no cargo process. The

# skips silently when cargo is absent; this one cannot skip.
