Installation

Add to your Cargo.toml:

[dependencies]
sensitive-rs = "0.5.0"

Quick Start

use sensitive_rs::Filter;

fn main() {
    let mut filter = Filter::new();
    filter.add_words(&["rust", "filter", "敏感词"]);

    let text = "hello rust, this is a filter demo 包含敏感词";
    let found = filter.find_all(text);
    println!("Found: {:?}", found);

    let cleaned = filter.replace(text, '*');
    println!("Cleaned: {}", cleaned);
}

Advanced Usage

Batch processing:

let texts = vec!["text1", "text2"];
let results = filter.find_all_batch( & texts);

Layered matching:

let layered = filter.find_all_layered("some long text");

Streaming large files:

use std::fs::File;
use std::io::BufReader;

let reader = BufReader::new(File::open("large.txt") ? );
let stream_results = filter.find_all_streaming(reader) ?;
