Struct FixedPhrase

Source
pub struct FixedPhrase { /* private fields */ }
Expand description

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::expr::{FixedPhrase, Expr};
use harper_core::Document;

let doc = Document::new_plain_english_curated("Hello, world!");
let phrase = FixedPhrase::from_phrase("Hello, world!");
assert!(phrase.run(0, doc.get_tokens(), doc.get_source()).is_some());

Implementations§

Source§

impl FixedPhrase

Source

pub fn from_phrase(text: &str) -> Self

Creates a FixedPhrase from a plaintext string. Uses plain English tokenization rules.

Source

pub fn from_document(doc: &Document) -> Self

Creates a FixedPhrase from a pre-tokenized document. Allows custom tokenization by creating a Document first.
