Struct FixedPhrase

pub struct FixedPhrase { /* private fields */ }

Matches a fixed sequence of tokens as they appear in the input. Case-insensitive for words but maintains exact matching for other token types.

Example

use harper_core::patterns::{FixedPhrase, Pattern};
use harper_core::Document;

let doc = Document::new_plain_english_curated("Hello, world!");
let phrase = FixedPhrase::from_phrase("Hello, world!");
assert!(phrase.matches(doc.get_tokens(), doc.get_source()).is_some());
