NAME

Wasm::Func - Interface to WebAssembly Memory

VERSION

version 0.17

SYNOPSIS

Call Wasm from Perl:

 use Wasm
   -api => 0,
   -wat => q{
     (module
       (func (export "add") (param i32 i32) (result i32)
        local.get 0
        local.get 1
        i32.add)
     )
   }
 ;
 
 print add(1,2), "\n";  # 3

Call Perl from Wasm:

 sub hello {
   print "hello world!\n";
 }
 
 use Wasm
   -api => 0,
   -wat => q{
     (module
       (func $hello (import "main" "hello"))
       (func (export "run") (call $hello))
     )
   }
 ;
 
 run();   # hello world!

DESCRIPTION

This documents the interface to functions for Wasm. Each function exported from WebAssembly is automatically imported into Perl space as a Perl subroutine. Wasm modules can import Perl subroutines using their standard import process.
