Struct wasm3::Runtime

pub struct Runtime { /* private fields */ }

A runtime context for wasm3 modules.

Implementations

impl Runtime

pub fn new(environment: &Environment, stack_size: u32) -> Result<Self>

Creates a new runtime with the given stack size in slots.

Errors

This function will error on memory allocation failure.

pub fn parse_and_load_module<TData: Into<Box<[u8]>>>(
    &self,
    bytes: TData
) -> Result<Module<'_>>

Parses and loads a module from bytes.

pub fn load_module(&self, module: ParsedModule) -> Result<Module<'_>>

Loads a parsed module returning the module if unsuccessful.

Errors

This function will error if the module’s environment differs from the one this runtime uses.

pub fn find_function<ARGS, RET>(
    &self,
    name: &str
) -> Result<Function<'_, ARGS, RET>> where
    ARGS: WasmArgs,
    RET: WasmType, 

Looks up a function by the given name in the loaded modules of this runtime. See Module::find_function for possible error cases.

pub fn memory(&self) -> *const [u8]

Returns the raw memory of this runtime.

Safety

The returned pointer may get invalidated when wasm function objects are called due to reallocations.

pub fn memory_mut(&self) -> *mut [u8]

Returns the raw memory of this runtime.

Safety

The returned pointer may get invalidated when wasm function objects are called due to reallocations.

Trait Implementations

impl Debug for Runtime

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for Runtime

fn drop(&mut self)

Executes the destructor for this type.
