Trait WasmInstance 

pub trait WasmInstance: Send {
    // Required methods
    fn call(
        &self,
        method: InvokeMethod<'_>,
        data: &[u8],
    ) -> Result<Vec<u8>, Error>;
    fn get_global_const(&self, name: &str) -> Result<Option<Value>, Error>;

    // Provided method
    fn call_export(&self, method: &str, data: &[u8]) -> Result<Vec<u8>, Error> { ... }
}

A trait that defines an abstract wasm module instance.

This can be implemented by an execution engine.

Required Methods

fn call(&self, method: InvokeMethod<'_>, data: &[u8]) -> Result<Vec<u8>, Error>

Call a method on this WASM instance.

Before execution, instance is reset.

Returns the encoded result on success.

fn get_global_const(&self, name: &str) -> Result<Option<Value>, Error>

Get the value from a global with the given name.

This method is only suitable for getting immutable globals.

Provided Methods

fn call_export(&self, method: &str, data: &[u8]) -> Result<Vec<u8>, Error>

Call an exported method on this WASM instance.

Before execution, instance is reset.

Returns the encoded result on success.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
