An enum of every supported language in the current feature set.

An instance of the respective tree-stter Language can be obtained with the get method.

You can also get a Lang from its name using for_name, or for a FileType using for_file_type. See the docs for each variant to see its “name” and the supported file types. Both of these require the SupportedLanguage trait to be in scope.

See LANGUAGES for a list containing all variants and LANGUAGE_NAMES for a list of all valid names.

The enum is marked as non-exhaustive for two reasons:

1. New languages may be added in the future
2. The variants are enabled/disabled by features

Example

use syntastica_parsers_git::{Lang, LANGUAGES, LANGUAGE_NAMES};
use syntastica_core::language_set::{SupportedLanguage, FileType};

// you can get a `Lang` from its name
assert_eq!(Lang::Rust, Lang::for_name("rust", &()).unwrap());
// and for a file type
assert_eq!(Some(Lang::Rust), Lang::for_file_type(FileType::Rust, &()));

// `LANGUAGES` is a list of all variants,
// `LANGUAGE_NAMES` is a list of all variant names
for (&lang, &name) in LANGUAGES.iter().zip(LANGUAGE_NAMES) {
    assert_eq!(lang, Lang::for_name(name, &()).unwrap());

    // `Lang` instances can be turned into strings
    assert_eq!(lang, Lang::for_name(<Lang as SupportedLanguage<'_, ()>>::name(&lang), &()).unwrap());
    assert_eq!(lang, Lang::for_name(lang.to_string(), &()).unwrap());
    assert_eq!(lang, Lang::for_name(lang.as_ref(), &()).unwrap());
    let lang_name: &'static str = lang.into();
    assert_eq!(lang, Lang::for_name(lang_name, &()).unwrap());
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
