language documentation Type system

From Type system

(Type system) method enums

Defined as:

method enums()

Returns the list of enum-pairs.

enum Mass ( mg => 1/1000, g => 1/1, kg => 1000/1 );
say Mass.enums; # OUTPUT: «{g => 1, kg => 1000, mg => 0.001}␤»

enum Bool

From Bool

(Bool) routine enums

method enums(--> Hash:D)

Returns a Hash of enum-pairs. Works on both the Bool type and any key.

say Bool.enums;                                   # OUTPUT: «{False => 0, True => 1}␤»
say False.enums;                                  # OUTPUT: «{False => 0, True => 1}␤»

role Enumeration

From Enumeration

(Enumeration) method enums

Defined as:

method enums()

Returns a Map of enum values. Works both on the enum type and any key.

enum Mass ( mg => 1/1000, g => 1/1, kg => 1000/1 );
say Mass.enums; # OUTPUT: «Map.new((g => 1, kg => 1000, mg => 0.001))␤»
say g.enums;    # OUTPUT: «Map.new((g => 1, kg => 1000, mg => 0.001))␤»
