NAME
Option::Option
SYNOPSIS
Provides objects that can hold results that can be unwrapped similar to Rust
use Option::Option;
my $option = Option::Option->new("something");
# This croaks:
print $var;
# This works
my $var = $option->unwrap();
print $var;
# This also works and has a helpful error message
my $var = $option->expect("get my something");
print $var;

METHODS
- new()
-
Creates a new object with a variable
- unwrap()
-
Checks if the variable is defined and if it is, returns it. If not defined, croaks.
- expect($msg)
-
Checks if the variable is defined and if it is, returns it. If not defined, croaks with error message.
- toString()
-
Dies with an error message, describing that the object was attempted to be used in a scalar context without unwrapping. This subroutine is not meant to be used directly.
my $var = Option::Option->new("something"); my $concat = $var . " wicked this way comes"; # dies with error message during the concatenation
