Why does attributes_to_crop has a different prototype than attributes_to_highlight

[bidoubiwa]

attributes_to_crop and attributes_to_highlight have the same type as per the documentation

meilisearch-rust/src/search.rs

Line 175 in 0d1a82e

pub attributes_to_crop: Option<Selectors<&'a [AttributeToCrop<'a>]>>,

and here

meilisearch-rust/src/search.rs

Line 187 in 0d1a82e

pub attributes_to_highlight: Option<Selectors<&'a [&'a str]>>,

I was wondering if there was another reason why these two attributes have different types?
