Previously, since the graph contained only identifiers, discovered roots were stored in a separate vector and exposed to the caller. This not only leaked details, but added complexity; this was left over from the refactoring of the proof-of-concept linker some time ago. This moves the root management into the ASG itself, mostly, with one item being left over for now in the asg_builder (eligibility classifications). There are two roots that were added automatically: - __yield - __worksheet The former has been removed and is now expected to be explicitly mapped in the return map, which is now enforced with an extern in `core/base`. This is still special, in the sense that it is explicitly referenced by the generated code, but there's nothing inherently special about it and I'll continue to generalize it into oblivion in the future, such that the final yield is just a convention. `__worksheet` is the only symbol of type `IdentKind::Worksheet`, and so that was generalized just as the meta and map entries were. The goal in the future will be to have this more under the control of the source language, and to consolodate individual roots under packages, so that the _actual_ roots are few. As far as the actual ASG goes: this introduces a single root node that is used as the sole reference for reachability analysis and topological sorting. The edges of that root node replace the vector that was removed. DEV-11864 |

TAME in Rust (TAMER)
TAME was written to help tame the complexity of developing comparative insurance rating systems. This project aims to tame the complexity and performance issues of TAME itself. TAMER is therefore more tame than TAME.
TAME was originally written in XSLT. For more information about the
project, see the parent README.md.
Building
To bootstrap from the source repository, run ./bootstrap.
To configure the build for your system, run ./configure. To build, run
make. To run tests, run make check.
You may also invoke cargo directly, which make will do for you using
options provided to configure.
Note that the default development build results in terrible runtime performance! See [#Build Flags][] below for instructions on how to generate a release binary.
Build Flags
The environment variable CARGO_BUILD_FLAGS can be used to provide
additional arguments to cargo build when invoked via make. This can be
provided optionally during configure and can be overridden when invoking
make. For example:
# release build
$ ./configure && make CARGO_BUILD_FLAGS=--release
$ ./configure CARGO_BUILD_FLAGS=--release && make
# dev build
$ ./configure && make
$ ./configure CARGO_BUILD_FLAGS=--release && make CARGO_BUILD_FLAGS=
Hacking
This section contains advice for those developing TAMER.
Running Tests
Developers should be using test-driven development (TDD). make check will
run all necessary tests.
Code Format
Rust provides rustfmt that can automatically format code for you. This
project mandates its use and therefore eliminates personal preference in
code style (for better or worse).
Formatting checks are run during make check and, on failure, will output
the diff that would be applied if you ran make fmt (or make fix); this
will run cargo fmt for you (and will use the binaries configured via
configure).
Since developers should be doing test-driven development (TDD) and therefore
should be running make check frequently, the hope is that frequent
feedback on formatting issues will allow developers to quickly adjust their
habits to avoid triggering formatting errors at all.
If you want to automatically fix formatting errors and then run tests:
$ make fmt check
Benchmarking
Benchmarks serve two purposes: external integration tests (which are subject
to module visibility constraints) and actual benchmarking. To run
benchmarks, invoke make bench.
Note that link-time optimizations (LTO) are performed on the binary for benchmarking so that its performance reflects release builds that will be used in production.
The configure script will automatically detect whether the test feature
is unstable (as it was as of the time of writing) and, if so, will
automatically fall back to invoking nightly (by running cargo +nightly bench).
If you do not have nightly, run you install it via rustup install nightly.
