Module lang 

Language detection by file extension.

Maps file extensions to supported language identifiers.

All languages are unconditionally compiled in. The historical lang-* Cargo feature gates have been removed; every registered extension is always available at runtime. This simplifies the build matrix and guarantees that callers never get a feature-gate error for a language that “should” be supported.

Functions

language_for_extension

Returns the language identifier for the given file extension, or None if unsupported.

supported_extensions

Returns all file extensions supported by the compiled feature set.

supported_languages

Returns a static slice of all supported language names.
