NAME

Mojo::Collection::Role::Set - Set operations for collections

DESCRIPTION

A role for Mojo::Collection objects to provide set operations "diff", "duplicates", "intersect", "sym_diff" and "union".

SYNOPSIS

# [2]
c(2, 3, 5, 7, 11, 13, 17)->with_roles('+Set')
  ->interset(c(grep { ! $_ % 2 } 1 .. 20))->to_array;

EXPORTED FUNCTIONS

set

# import
use Mojo::Collection::Role::Set 'set';
# [1, 2, 3, 4, 5]
set(1 .. 5);

Like the Mojo::Collection c(), this is sugar for creating a collection with this role.

METHODS

diff

# [1, 2, 3, 4, 5, 6, 7, 8, 9]
c(1 .. 20)->with_roles('+Set')->diff(c(10 .. 30))->to_array;

The values in a Mojo::Collection that are not in the second one.
