VERSION

version 0.23

SYNOPSIS


            

              
              
use Wasm::Wasmtime;
my $config = Wasm::Wasmtime::Config->new;
$config->wasm_multi_value(1);
my $engine = Wasm::Wasmtime::Engine->new($config);

DESCRIPTION

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