Struct Environment

pub struct Environment<'a>(/* private fields */);

Implementations

impl Environment<'_>

pub fn from_raw_pointer(raw_pointer: EnvironmentPointer) -> Result<Self>

pub fn from_instance(instance: &Instance<'_>) -> Result<Self>

pub fn get_or_initialize_custom_data(&self) -> Result<&CustomData>

pub unsafe fn convert_to_native_pointer<T>( &self, address: WasmPointer, ) -> Option<*mut T>

Safety

This function is unsafe because it is not checked that the address is valid. Please use Validate_WASM_pointer to check the address.

pub unsafe fn convert_to_wasm_pointer<T>( &self, pointer: *const T, ) -> WasmPointer

Safety

This function is unsafe because it is not checked that the address is valid. Please use Validate_WASM_pointer to check the address.

pub fn validate_wasm_pointer( &self, address: WasmPointer, size: WasmUsize, ) -> bool

pub fn validate_native_pointer<T>(&self, pointer: *const T, size: u64) -> bool

pub fn call_indirect_function( &self, function_index: u32, parameters: &Vec<WasmValue>, ) -> Result<()>

Make an indirect function call (call a function by its index which is not exported). For exported functions use Call_export_function.

pub fn create_environment(&self, stack_size: usize) -> Result<Self>

Create a new execution environment. This environment should be initialized with Initialize_thread_environment and deinitialized with Deinitialize_thread_environment.
