NAME

Array::Sorted::Map - Provide a Map interface for 2 sorted lists

SYNOPSIS

use Array::Sorted::Util;
use Array::Sorted::Map;

my @keys;
my @values;

inserts(@keys, "a", @values, 42);  # "inserts" from Array::Sorted::Util
inserts(@keys, "b", @values, 666);

my %map := Array::Sorted::Map.new(:$keys, :$values);

say %map<a>;  # 42;
say %map<b>;  # 666;
say %map<c>;  # Nil

say %map.keys;    # (a b)
say %map.values;  # (42 666)

DESCRIPTION

Array::Sorted::Map provides a class that can be used to provide a Map interface to two sorted lists: one for keys, and one for values, such as typically created / maintained by the subroutines offered by the Array::Sorted::Util distribution.

Optionally, a :cmp argument can be specified, indicating the logic that should be used for comparing elements from the keys. By default, the infix:<cmp> will be assumed.
