# ArrowPipe: Build complex pipelines easily
An [`Arrow`] is a function composition system that can be used to create
complex data processing pipelines.
## Installation
Add the following to your `Cargo.toml`:
```toml
[dependencies]
arrowpipe = { git = "https://github.com/Brian3647/arrowpipe" }
```
## Example
```rust
use arrowpipe::Arrow;
fn add_one(x: i32) -> i32 {
x + 1
}
fn double(x: i32) -> i32 {
x * 2
}
let mut arrow = Arrow::new(add_one);
arrow.symbiotize(Arrow::new(double));
assert_eq!(arrow.shoot(1), 3);
```
## Order of execution example:
```rust
use arrowpipe::Arrow;
fn add_one(x: i32) -> i32 {
x + 1
}
let mut first = Arrow::new(add_one); // Second: 2 -> 3
let mut second = Arrow::new(add_one); // First: 1 -> 2
second.symbiotize(first);
assert_eq!(second.shoot(1), 6);
```
## Why?
This is specially useful for long pipelines like a build system. With the `Arrow` struct, you can simply add another `Arrow` to an existing one to have a new step.
