Implementations

impl ModuleInstance

pub fn exports(&self) -> &ExportInstance

Get the module’s exports

pub fn get_func(&self, store: &Store, name: &str) -> Result<FuncHandle>

Get an exported function by name

pub fn get_typed_func<P, R>( &self, store: &Store, name: &str ) -> Result<TypedFuncHandle<P, R>>

where P: IntoWasmValueTuple, R: FromWasmValueTuple,

Get a typed exported function by name

pub fn get_start_func(&mut self, store: &Store) -> Result<Option<FuncHandle>>

Get the start function of the module

Returns None if the module has no start function If no start function is specified, also checks for a _start function in the exports (which is not part of the spec, but used by llvm)

See https://webassembly.github.io/spec/core/syntax/modules.html#start-function

pub fn start(&mut self, store: &mut Store) -> Result<Option<()>>

Invoke the start function of the module

Returns None if the module has no start function

See https://webassembly.github.io/spec/core/syntax/modules.html#syntax-start
