Mike Gerwitz 0f20f22cfb tamer: diagnose::Diagnostic: Remove Error trait bound
Diagnostic events need not be errors.  While that was the original intent,
it'd also be nice to be able to use the diagnostic system for any type of
logging, where the verbosity level would determine the type of report that
is output (whether source information should be provided).

Then we could have e.g. AirAggregate produce events describing what actions
are occurring, which could be much more useful than a trace in many
contexts, and would be able to operate via a runtime toggle/filter without
having an adverse effect on performance (since the diagnostic rendering
itself is the hit; the underlying data are cheap).

Anyway---I'm addressing this now to generalize the reporter in the lowering
pipeline, so that it can report on not just errors but anything.

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.
