### Detector struct implementation with allowlist and denylist examples

Source: https://docs.rs/whatlang/latest/src/whatlang/core/detector.rs.html

The full source code of the Detector struct, including constructors with_allowlist and with_denylist, and methods detect, detect_lang, and detect_script. The doc comments include examples for using with_allowlist and with_denylist. The code also includes unit tests for detect_script, detect_lang, and detect.

```rust
use crate::Lang;
use crate::core;
use crate::core::FilterList;
use crate::core::Info;
use crate::core::Options;
use crate::scripts::{Script, detect_script};

/// Configurable structure that holds detection options and provides functions
/// to detect language and script.
/// # Examples
/// Specifying an allowlist:
///
/// 
/// use whatlang::{Detector, Lang};
///
/// // Create detector with allowlist
/// let detector = Detector::with_allowlist(vec![Lang::Eng, Lang::Rus]);
/// let lang = detector.detect_lang("That is not Russian");
/// assert_eq!(lang, Some(Lang::Eng));
/// 
///
/// Specifying a blacklist:
///
/// 
/// use whatlang::{Detector, Lang};
///
/// let detector = Detector::with_denylist(vec![Lang::Eng, Lang::Ita]);
/// let lang = detector.detect_lang("Jen la trinkejo fermitis, ni iras tra mallumo kaj pluvo.");
/// assert_eq!(lang, Some(Lang::Epo));

```rust
#[test]
    fn test_detect_with_options_with_filter_list_except_none() {
        {
            // All languages with Hebrew script are filtered out, so result must be None

            let options = Options::new().set_filter_list(filter_list);
            let output = detect_with_options(text, &options);
            assert_eq!(output, None);
        }

        {
            // All Latin languages are filtered out
            let text = "Mit dem Wissen wächst der Zweifel";
            let filter_list = FilterList::deny(Script::Latin.langs().to_owned());
            let options = Options::new().set_filter_list(filter_list);
            let output = detect_with_options(text, &options);
            assert_eq!(output, None);
        }
    }

### Detector::with_allowlist

Source: https://docs.rs/whatlang

Creates a Detector with an allowlist of languages to consider during detection. The detector can then be used to detect language from text.

```APIDOC
## Detector::with_allowlist

### Function Signature
`pub fn with_allowlist(langs: Vec<Lang>) -> Detector`

### Parameters

### Returns
- **Detector** - A configured `Detector` instance.

### Example
```rust
use whatlang::{Detector, Lang};

let allowlist = vec![Lang::Eng, Lang::Rus];
let detector = Detector::with_allowlist(allowlist);
let lang = detector.detect_lang("There is no reason not to learn Esperanto.");
assert_eq!(lang, Some(Lang::Eng));
```
```

--------------------------------

### Detect language using Detector with allowlist

Source: https://docs.rs/whatlang

Shows how to use the Detector struct with an allowlist to restrict detection to specific languages.

```rust
use whatlang::{Detector, Lang};

let allowlist = vec![Lang::Eng, Lang::Rus];

// You can also create detector using with_denylist function
let detector = Detector::with_allowlist(allowlist);
let lang = detector.detect_lang("There is no reason not to learn Esperanto.");
assert_eq!(lang, Some(Lang::Eng));
```

--------------------------------

### Iterate over all languages

Source: https://docs.rs/whatlang/latest/whatlang/enum.Lang.html

    println!("{}", lang);
}
```

### Script enum: all(), name(), langs(), Display, FromStr

Source: https://docs.rs/whatlang/latest/src/whatlang/scripts/script.rs.html

Defines the Script enum with 25 writing-system variants and a VALUES array. Script::all() returns the static slice of all variants, name() returns the canonical name, and langs() delegates to lang_mapping::script_langs. FromStr parses case-insensitive trimmed names and returns ParseError::Script for unknown input; Display writes the name().

```rust
use std::fmt;
use std::str::FromStr;

use super::lang_mapping;
use crate::Lang;
use crate::error::ParseError;

/// Represents a writing system (Latin, Cyrillic, Arabic, etc).
