Struct WasmEngine 

pub struct WasmEngine { /* private fields */ }

A WASM checker plugin loaded via Extism.

The plugin must export a check function that accepts a JSON string {"text": "...", "language_id": "..."} and returns a JSON array of diagnostics matching the ExternalDiagnostic schema.

Implementations

impl WasmEngine

pub fn new(name: String, wasm_path: PathBuf) -> Result<Self>

Create a new WASM engine from a .wasm file path.

pub fn from_bytes(name: String, wasm_bytes: &[u8]) -> Result<Self>

Create a new WASM engine from raw bytes (useful for testing).

Trait Implementations

impl Engine for WasmEngine

fn name(&self) -> &'static str

fn check<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, text: &'life1 str, language_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<Diagnostic>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

fn supported_languages(&self) -> Vec<&'static str>

BCP-47 primary subtags this engine supports. Empty = all languages.

fn check_many<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, texts: &'life1 [String], language_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Vec<Result<Vec<Diagnostic>>>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Check a batch of independent texts, returning one result per input in order.
