use country_emoji::{flag, code, name};

// Generate flag emoji from country code
assert_eq!(flag("US"), Some("🇺🇸".to_string()));

// Extract country code from flag emoji
assert_eq!(code("🇨🇦"), Some("CA"));

// Get country name from code
assert_eq!(name("DE"), Some("Germany"));

// Convert country name to code
assert_eq!(code("Japan"), Some("JP"));
```### Advanced Fuzzy Matching

The library handles many name variations and formats intelligently:

```rust
use country_emoji::code;

// Alternative names and abbreviations
assert_eq!(code("UK"), Some("GB"));           // → 🇬🇧
assert_eq!(code("UAE"), Some("AE"));          // → 🇦🇪
assert_eq!(code("Russia"), Some("RU"));       // → 🇷🇺

// Government titles and formal names
assert_eq!(code("Republic of Moldova"), Some("MD"));                        // → 🇲🇩
assert_eq!(code("Democratic People's Republic of Korea"), Some("KP"));      // → 🇰🇵
assert_eq!(code("United States of America"), Some("US"));                   // → 🇺🇸

// Comma-reversed formats
assert_eq!(code("Virgin Islands, British"), Some("VG"));
assert_eq!(code("Korea, Republic of"), Some("KR"));

// Saint/St. normalization
assert_eq!(code("Saint Lucia"), Some("LC"));
assert_eq!(code("St. Lucia"), Some("LC"));
assert_eq!(code("St Lucia"), Some("LC"));

// And/ampersand equivalence
assert_eq!(code("Bosnia and Herzegovina"), Some("BA"));
assert_eq!(code("Bosnia & Herzegovina"), Some("BA"));

// Diacritic handling
assert_eq!(code("Cote d'Ivoire"), Some("CI"));
assert_eq!(code("Côte d'Ivoire"), Some("CI"));

// Partial matching for unique names
assert_eq!(code("Vatican"), Some("VA"));

use country_emoji::{code_to_flag, flag_to_code, name_to_code, code_to_name, is_code, is_country_flag};

assert_eq!(code_to_flag("FR"), Some("🇫🇷".to_string()));
assert_eq!(flag_to_code("🇮🇹"), Some("IT"));
assert_eq!(name_to_code("Spain"), Some("ES"));
assert_eq!(code_to_name("BR"), Some("Brazil"));

assert!(is_code(Some("CA")));   // ✅ Valid
assert!(is_country_flag("🇯🇵"));  // ✅ Valid

use country_emoji::code;

// Invalid inputs
assert_eq!(code("ZZ"), None);       // ❌ Invalid
assert_eq!(code("Atlantis"), None); // ❌ Non-existent

// Ambiguous inputs (prevents false matches)
assert_eq!(code("Korea"), None);   // ❓ Ambiguous (🇰🇵 or 🇰🇷?)
assert_eq!(code("United"), None);  // ❓ Too vague
