Struct tinywasm::Store

pub struct Store { /* private fields */ }

Global state that can be manipulated by WebAssembly programs

Data should only be addressable by the module that owns it

Note that the state doesn’t do any garbage collection - so it will grow indefinitely if you keep adding modules to it. When calling temporary functions, you should create a new store and then drop it when you’re done (e.g. in a request handler)

See https://webassembly.github.io/spec/core/exec/runtime.html#store

Implementations

impl Store

pub fn new() -> Self

Create a new store

pub fn get_module_instance( &self, addr: ModuleInstanceAddr ) -> Option<&ModuleInstance>

Get a module instance by the internal id

impl Store

pub fn id(&self) -> usize

Get the store’s ID (unique per process)

pub fn get_global_val(&self, addr: usize) -> Result<RawWasmValue>

Get the global at the actual index in the store

Trait Implementations

impl Debug for Store

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

Formats the value using the given formatter.

impl Default for Store

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Store

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
