# FastRSS
Parse RSS feeds very quickly
* This is rust NIF built using [rustler](https://github.com/rusterlium/rustler)
* Uses the [RSS](https://crates.io/crates/rss) crate to do the actual RSS parsing
**Speed**
Currently this is already much faster than most of the pure elixir/erlang packages out there. In benchmarks there are speed improvements anywhere between **5.94x - 49.03x** over the next fastest package ([feeder_ex])(https://github.com/manukall/feeder_ex) that was tested.
Compared to the slowest elixir options tested ([feed_raptor](https://github.com/merongivian/feedraptor), [elixir_feed_parser](https://github.com/fdietz/elixir-feed-parser)), FastRSS was sometimes **255.53x** faster and used **5,412,308.17x** less memory *(0.00156 MB vs 8423.70 MB)*.
## Installation
This package is available on [hex](https://hex.pm/packages/fast_rss).
It can be installed by adding `fast_rss` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:fast_rss, "~> 0.2.0"}
]
end
```
You also need the rust compiler installed: https://www.rust-lang.org/tools/install
```bash
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
## Usage
There is only one function it takes an RSS string and outputs an `{:ok, map()}` with string keys.
```elixir
iex(1)> {:ok, map_of_rss} = FastRSS.parse("...rss_feed_string...")
iex(2)> Map.keys(map_of_rss)
