Scala3 TypeMap

This project is a simple implementation of a type-level map in Scala3, using macros. Inspired by the rust crate anymap.

INSTALL

Clone typemap

$ git clone https://github.com/lichess-org/TypeMap

Start sbt in typemap directory

$ sbt

In the sbt shell, to compile typemap and examples, run

sbt:typemap> build

To run the tests

sbt:typemap> test

To compile or test the examples

sbt:typemap> examples / compile (or test)

To run benchmarks:

sbt:typemap> bench / Jmh / run

Or to ouput a json file

sbt:typemap> bench / Jmh / run -rf json

To run quick benchmarks (results may be inaccurate):

sbt:typemap> bench / Jmh / run -i 1 -wi 1 -f1 -t1

To run benchmarks for a specific class:

sbt:typemap> bench / Jmh / run -rf json .*PlayBench.*

To run scalafmt:

sbt:typemap> fmt

To run sbt-coverage

$ ./coverage.sh

### Usage

```scala
val map: TypeMap[Int | String, String] = TypeMap.empty
map.put[Int]("1")
assertEquals(map.get[Int], Some("1"))
assertEquals(map.get[String], None)
// does not compile, as expected
map.get[Float]
