# # cargo-make config for CI.
#
# ## Variables to maintain
# * `MSRV`
#     + Minimal supported rust version.
#     + This should be consistent with `package.rust-version` field of `Cargo.toml`.
#
# ## Controllable variables
# * `VERBOSE`
#     + If set to non-`false` or non-`0`, `--verbose` options are added for build and test.
#
# ## Profiles
# Profiles are mainly used to change features and dependencies.
#
# * `default`
#     + Default features.
#     + Up-to-date deps.
# * `feat-none`
#     + No features.
#     + Up-to-date deps.
# * `feat-alloc`
#     + `alloc` feature.
#     + Up-to-date deps.
# * `feat-std`
#     + `std` feature.
#     + Up-to-date deps.
# * `feat-serde`
#     + `serde` feature.
#     + Up-to-date deps.
# * `feat-serde-alloc`
#     + `serde-alloc` feature.
#     + Up-to-date deps.
# * `feat-serde-std`
#     + `serde-std` feature.
#     + Up-to-date deps.
# * `feat-serde-alloc-independent`
#     + `serde,alloc` features, without `serde-alloc`.
#     + Up-to-date deps.
# * `feat-serde-std-independent`
#     + `serde,std` features, without `serde-std`.
#     + Up-to-date deps.
# * `feat-time03`
#     + `time03` feature.
#     + Up-to-date deps.
# * `feat-all`
#     + All features.
#     + Up-to-date deps.
# * `minimal-deps-feat-none`
#     + No features.
#     + Minimal versions deps.
# * `minimal-deps-default`
#     + Default features.
#     + Minimal versions deps.
# * `minimal-deps-feat-all`
#     + All features.
#     + Minimal versions deps.
# * `feat-time03`
#     + `time03` feature.
#     + Minimal versions deps.
#
# ## Tasks
#
# ### For CLI
# * `manual-ci-all`
#     + Invokes all required CI tasks, with required rust versions.
# * `ci-all-profiles`
#     + Invokes required CI tasks for all profiles.
# * `ci-all-profiles`
#     + Invokes required CI tasks for all profiles.
#
# ### For automated CI
# * `ci-once`
#     + CI task that should be run at least once for one commit.
#     + This does not need to be run with multiple tasks, or
#       with multiple rust versions.
# * `ci`
#     + CI task that should (or recommended to) be run for each profiles and/or
#       for each toolchain.
