SYNOPSIS

 use Wasm::Wasmtime;
 
 my $module = Wasm::Wasmtime::Module->new( wat => q{
   (module
    (func (export "add") (param i32 i32) (result i32)
      local.get 0
      local.get 1
      i32.add)
   )
 });
 
 my $exports = $module->exports;   # Wasm::Wasmtime::Module::Exports
 
 my $type1      = $exports->add;   # this is the Wasm::Wasmtime::FuncType for add
 my $type2      = $exports->{add}; # this is also the Wasm::Wasmtime::FuncType for add
 my $exporttype = $exports->[0];   # this is the Wasm::Wasmtime::ExportType for add

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 the exports from a module. It can be used in a number of different ways.

autoload methods
 my $foo = $module->exports->foo;

Calling the name of an export as a method returns the Wasm::Wasmtime::ExternType for the export.

As a hash reference
 my $foo = $module->exports->{foo};

Using the Exports class as a hash reference allows you to get exports that might clash with common Perl methods like new, can, DESTROY, etc. The Wasm::Wasmtime::ExternType will be returned.

An array reference
 my $foo = $module->exports->[0];

This will give you the list of exports in the order that they are defined in your WebAssembly. The object returned is a Wasm::Wasmtime::ExportType, which is essentially a name and a Wasm::Wasmtime::ExternType.
