VERSION

version 0.24

SYNOPSIS

 use Wasm::Wasmtime;

 my $instance = Wasm::Wasmtime::Instance->new($module, $store, []);

DESCRIPTION

WARNING: WebAssembly and Wasmtime are a moving target and the interface for these modules is under active development. Use with caution.

This class represents an instance of a WebAssembly module Wasm::Wasmtime::Module.

CONSTRUCTOR

new

 my $instance = Wasm::Wasmtime::Instance->new(
   $module,    # Wasm::Wasmtime::Module
   $store      # Wasm::Wasmtime::Store
 );
 my $instance = Wasm::Wasmtime::Instance->new(
   $module,    # Wasm::Wasmtime::Module
   $store,     # Wasm::Wasmtime::Store
   \@imports,  # array reference of Wasm::Wasmtime::Extern (or shortcuts)
 );

Create a new instance. @imports should match the imports specified by $module. Shortcuts: a plain code reference for a function import, a scalar reference or undef for a memory import.
