# About
Stop words are words that don't carry much meaning, and are typically removed as a preprocessing step before text
analysis or natural language processing. This crate contains common stop words for a variety of languages. This crate uses stop word
lists from [Stopwords ISO](https://github.com/stopwords-iso) and also from [NLTK](https://www.nltk.org/).
# Usage
Using this crate is fairly straight-forward:
```rust
use stop_words;
fn main() {
// Get the stop words
let words = stop_words::get(stop_words::LANGUAGE::English);
// Print them
for word in words {
println!("{}", word)
}
}
```
The function ``get`` will pull stop words from using an enum from `LANGUAGE` as an input. The function `get_iso` will allow you to feed in a two letter ISO code as followed:
```rust
let words = stop_words::get_iso("en");
```
If you prefer to have a ``HashSet<String>`` of words instead of a ``Vec<String>``, you can do this:
```rust
let vec = stop_words::get(English);
let hash = vec.into_iter().collect();
```
