Algebraic Data Types (ADTs)

In OCaml, you can define algebraic data types using the type keyword. For example:

type shape = Circle of float | Rectangle of float * float

In Rust, you achieve a similar effect using enums:

enum Shape {
    Circle(f64),
    Rectangle(f64, f64),
}

Pattern Matching

OCaml allows pattern matching directly on data constructors:

match shape with
| Circle r -> ...
| Rectangle (w, h) -> ...

In Rust, pattern matching is also supported but with a slightly different syntax:

match shape {
    Shape::Circle(r) => ...,
    Shape::Rectangle(w, h) => ...,
}

Reference: Rust Documentation on Pattern Matching

First-Class Functions

In OCaml, first-class functions can be defined and passed around easily:

let apply f x = f x

In Rust, you can define a function that takes another function as an argument:

fn apply(f: fn(i32) -> i32, x: i32) -> i32 {
    f(x)
}

Reference: OCaml Documentation on Functions

Immutable vs Mutable Data

OCaml variables are immutable by default:

let x = 5; x := 10  (* This will raise an error *)

In Rust, you can declare mutable variables using mut:

let mut x = 5; x = 10;

Reference: Rust Documentation on Variables

Type Inference

OCaml has powerful type inference:

let x = 42  (* Type is inferred as int *)

In Rust, you can also infer types, but sometimes you need to specify them explicitly:

let x: i32 = 42;  // Type must be specified if not inferred

Reference: OCaml Documentation on Type Inference

Module System

OCaml has a module system that allows for encapsulation:

module M = struct
    let x = 5
end

In Rust, modules are defined using the mod keyword:

mod M {
    pub const X: i32 = 5;
}

Reference: Rust Documentation on Modules

Exception Handling

OCaml uses a try ... with construct for exception handling:

try ... with Failure -> ...

In Rust, you can use std::panic::catch_unwind for similar functionality:

std::panic::catch_unwind(|| {
    ...
}).unwrap_err();

Reference: OCaml Documentation on Exceptions

Higher-Kinded Types

OCaml supports higher-kinded types through polymorphic functions:

let f : ('a -> 'b) -> 'a -> 'b = ...

In Rust, you can achieve this with generics:

fn f<T, U>(x: T) -> U { ... }
