Implementations

impl AppService

pub fn new<C, S>( config: C, service_id: S, envs: HashMap<String, String>, ) -> Result<AppService, AppServiceError>

where C: TryInto<AppServiceConfig>, S: Into<String>, AppServiceError: From<<C as TryInto<AppServiceConfig>>::Error>,

Create Service with given modules and service id.

pub fn call( &mut self, func_name: impl AsRef<str>, arguments: Value, call_parameters: CallParameters, ) -> Result<Value, AppServiceError>

Call a specified function of loaded module by its name with arguments in json format.

pub fn call_with_ivalues( &mut self, func_name: impl AsRef<str>, arguments: &[IValue], call_parameters: CallParameters, ) -> Result<Vec<IValue>, AppServiceError>

Call a specified function of loaded module by its name with arguments in IValue format.

pub fn get_interface(&self) -> ServiceInterface

Return interface (function signatures and record types) of this service.

pub fn module_memory_stats(&self) -> MemoryStats<'_>

Return statistics of Wasm modules heap footprint. This operation is cheap.
