+# Rust
+
+Domain modeling, influenced by functional programming principles, aims to represent the business domain in the code accurately.
+[Rust](https://www.rust-lang.org/) is ideal thanks to its ownership model and type system, which enforce correctness and reliability - enabling you to eliminate many classes of bugs at compile-time, guarantying memory-safety and thread-safety.
+
+ - You can find the source code for the `fmodel-rust` [here](https://github.com/fraktalio/fmodel-rust)
+ - Publicly available at [crates.io](https://crates.io/crates/fmodel-rust) and

+## Decide
+
+`type DecideFunction<'a, C, S, E> = Box<dyn Fn(&C, &S) -> Vec<E> + 'a + Send + Sync>`
+
+On a higher level of abstraction, any information system is responsible for handling the intent (`Command`) and based on
+the current `State`, produce new facts (`Events`):
+
+- given the current `State/S` *on the input*,
+- when `Command/C` is handled *on the input*,
+- expect `Vec` of new `Events/E` to be published/emitted *on the output*
+
+## Evolve
+
+`type EvolveFunction<'a, S, E> = Box<dyn Fn(&S, &E) -> S + 'a + Send + Sync>`
+
+The new state is always evolved out of the current state `S` and the current event `E`:
+
+- given the current `State/S` *on the input*,
+- when `Event/E` is handled *on the input*,
+- expect new `State/S` to be published *on the output*
+
+Two functions are wrapped in a datatype class (algebraic data structure), which is generalized with three generic
+parameters:
+
+```rust
+pub struct Decider<'a, C: 'a, S: 'a, E: 'a> {
+    pub decide: DecideFunction<'a, C, S, E>,
+    pub evolve: EvolveFunction<'a, S, E>,
+    pub initial_state: InitialStateFunction<'a, S>,
+}
+```

+# TypeScript
+
+[TypeScript](https://www.typescriptlang.org/) understands JavaScript and uses type inference to give you great tooling without additional code.
+
+TypeScript is ideal thanks to its language features and type system, which enforce correctness and reduce the likelihood of bugs. 
+By modeling the domain accurately, we aim to use the TypeScript transpiler to catch errors early and prevent them from propagating to runtime.
