# Pipe Operator
Implementation of the pipe operator in Rust as a macro.
I wrote this because of 3 main things:
1. You cannot create methods on out of crate types. This means that chaining is harder.
2. [pipe_trait](https://crates.io/crates/pipe-trait) is nice but it requires currying for multi argument functions.
3. I want to write a plug like HTTP server
```rust
pipe!(
value,
function1(args),
function2(args)?, // notice the operator here
function3(args).await
)
```
The pipe operator is common in languages like elixir and haskell, they provide clarity and convience.
```elixir
conn
|> send_resp(404, "Not found")
```
## Examples
The argument will always go into the first function or method call.
```rust
pipe!(value, a.f().m()) // is equivalent to a.f(value).m()
```
To get around this we can make it a closure and pass the arg where we want.
```rust
