Struct WasmPluginBuilder

pub struct WasmPluginBuilder<E: Any + Send + Sized + 'static> { /* private fields */ }

Builder for creating WasmPlugin.

Implementations

impl<S: Any + Send + Sized + 'static> WasmPluginBuilder<S>

pub fn new() -> Self

Creates new WasmPluginBuilder.

pub fn new_with_store(store: Store) -> Self

Creates new WasmPluginBuilder and overrides default store with custom.

pub fn from_binary(self, bytecode: &[u8]) -> Result<Self, CompileError>

Available on crate feature compiler only.

Compiles bytecode with selected compiler. To change the compile use feature flags. Default compiler is cranelift.

pub unsafe fn from_serialized( self, data: &[u8], ) -> Result<Self, DeserializeError>

Creates plugin from bytes created by WasmPlugin::serialize.

Safety

See Module::deserialize.

pub unsafe fn from_serialized_compressed( self, compressed: &[u8], ) -> Result<Self, DeserializeError>

Available on crate feature flate2 only.

Creates plugin from compressed bytes created by WasmPlugin::serialize_compress.

Safety

See Module::deserialize.

pub unsafe fn from_serialized_file( self, path: impl AsRef<Path>, ) -> Result<Self, DeserializeError>

Creates plugin from bytes created by WasmPlugin::serialize_to_file.

Safety

See Module::deserialize_from_file.

pub unsafe fn from_serialized_file_compressed( self, path: impl AsRef<Path>, ) -> Result<Self, DeserializeError>

Available on crate feature flate2 only.

Creates plugin from compressed bytes created by WasmPlugin::serialize_to_file_compress.

Safety

See Module::deserialize.

pub fn with_state(self, state: S) -> Self

Creates a state that host function will have mutable access to. You HAVE to create the state. If you do not need it simply pass ().

pub fn with_imports( self, imports: impl FnOnce(&mut Store, &FunctionEnv<WasmEnv<S>>) -> Imports, ) -> Self

Creates imports i.e. host functions that guest imports. use make_imports! to create the closure.

pub fn with_exports( self, exports: impl IntoIterator<Item = Box<dyn GuestFunctionCreator>>, ) -> Self

Updates exports i.e. guest functions that host imports. use make_exports! to create the iterator.

pub fn finish(self) -> Result<WasmPlugin, InstantiationError>

Finishes building a WasmPlugin.
