NAME

results::wrap - wrap a method call in a Result

SYNOPSIS

Assuming that $object->foo( @args ) is a method call which might return a value or throw an exception, you can convert it to an ok/err Result using:

use results::wrap;

my $result = $object->results::wrap::foo( @args );

Or:

use results::wrap;

my $result = $object->results::wrap( foo => @args );

Or:

use results::wrap;

my $result = results::wrap { $object->foo( @args ) };

DESCRIPTION

This module uses AUTOLOAD to provide a Result wrapper around any method call.

It also provides a results::wrap sub which can be either passed a list of $invocant, $method, @args or a single coderef.

results::wrap is conveniently prototyped with (&) to that it can be called with a block.

my $result = results::wrap {
  if ( $failing_condition ) {
    die "Error";
  }
  else {
    return "Value";
  }
};
