NAME

Wasm::Wasmtime::Trap - Wasmtime trap class

VERSION

version 0.23

SYNOPSIS

use Wasm::Wasmtime;

my $store = Wasm::Wasmtime::Store->new;
my $trap = Wasm::Wasmtime::Trap->new(
  $store,
  "something went bump in the night\0",
);

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 a trap, usually something unexpected that happened in Wasm land. This is usually converted into an exception in Perl land, but you can create your own trap here.

CONSTRUCTORS

new

my $trap = Wasm::Wasmtime::Trap->new(
  $store,    # Wasm::Wasmtime::Store
  $message,  # Null terminated string
);

Create a trap instance. $message MUST be null terminated.

METHODS

message

my $message = $trap->message;

Returns the trap message as a string.

exit_status

my $status = $trap->exit_status;

If the trap was triggered by an exit call, this will return the exist status code. If it wasn't triggered by an exit call it will return undef.
