Mike Gerwitz 1be0f2fe70 tamer: asg::object: Move into graph module
The ASG delegates certain operations to Objects so that they may enforce
their own invariants and ontology.  It is therefore important that only
objects have access to certain methods on `Asg`, otherwise those invariants
could be circumvented.

It should be noted that the nesting of this module is such that AIR should
_not_ have privileged access to the ASG---it too must utilize objects to
ensure those invariants are enforced in a single place.

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.
