Enum Language 

#[non_exhaustive]
pub enum Language {
    TypeScript,
    Rust,
    Python,
    Go,
    Java,
    Kotlin,
    Ruby,

    C,
}

Source language of a graph node.

Used by the indexer dispatcher (Language::from_extension) and stored on the nodes.language column. The #[non_exhaustive] attribute prevents external crates from writing exhaustive matches — Phase 4 will add Go without a breaking change. Within the travsr workspace the compiler still enforces exhaustive matches, so adding a variant is a compile-time forcing function that updates every dispatch site.

See RFC-003 and ADR-005 for the design rationale.

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.

Implementations

impl Language

pub fn from_extension(ext: &str) -> Option<Language>

Map a file extension to a Language.

Returns None for unrecognised extensions — callers skip those files.

pub fn as_str(self) -> &'static str

Human-readable string stored in the nodes.language column.

pub fn from_str(s: &str) -> Option<Language>

Parse from the storage string produced by Language::as_str.

Trait Implementations

impl Clone for Language

fn clone(&self) -> Language

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Language

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Language

fn deserialize<__D>( __deserializer: __D, ) -> Result<Language, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Language

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Language

fn eq(&self, other: &Language) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Language

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Language

impl Eq for Language

impl StructuralPartialEq for Language
