## `cuprate-benchmark`
This crate links all benchmarks together into a single binary that can be run as: `cuprate-benchmark`.
`cuprate-benchmark` will run all enabled benchmarks sequentially and print data at the end.
## Benchmarks
Benchmarks are opt-in and enabled via features.
| Feature | Enables which benchmark crate? |
|----------|--------------------------------|
| example | cuprate-benchmark-example |
| database | cuprate-benchmark-database |
## Features
These are features that aren't for enabling benchmarks, but rather for other things.
Since `cuprate-benchmark` is built right before it is ran,
these features almost act like command line arguments.
| Features | Does what |
|----------|-----------|
| json | Prints JSON timings instead of a markdown table
| trace | Use the `trace` log-level
| debug | Use the `debug` log-level
| warn | Use the `warn` log-level
| info | Use the `info` log-level (default)
| error | Use the `error` log-level

## `cuprate-benchmark-lib`
This crate is the glue between
[`cuprate-benchmark`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/bin)
and all the benchmark crates.
It defines the [`crate::Benchmark`] trait, which is the behavior of all benchmarks.
See the [`cuprate-benchmark-example`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/example)
crate to see an example implementation of this trait.
After implementing this trait, a few steps must
be done such that the `cuprate-benchmark` binary
can actually run your benchmark crate; see the
[`Benchmarking` section in the Architecture book](https://architecture.cuprate.org/benchmarking/intro.html)
to see how to do this.

## `cuprate-criterion-example`
An example of using Criterion for benchmarking Cuprate crates.
Consider copy+pasting this crate to use as a base when creating new Criterion benchmark crates.
## `src/`
Benchmark crates have a `benches/` ran by `cargo bench`, but they are also crates themselves,
as in, they have a `src` folder that `benches/` can pull code from.
The `src` directories in these benchmarking crates are usually filled with
helper functions, types, etc, that are used repeatedly in the benchmarks.
## `benches/`
These are the actual benchmarks ran by `cargo bench`.
