NAME

Hydrogen::Topic::Counter - functions from Hydrogen::Counter applied to $_

VERSION

This documentation is for Hydrogen::Topic::Counter 0.016, which is based on Sub::HandlesVia::HandlerLibrary::Counter 0.037.

FUNCTIONS

Each function implicitly operates on $_, expecting it to be an integer.

dec( $amount? )

Operates on $_, which must be an integer.

Arguments: Optional[Int].

Decrements the counter by $amount, or by 1 if no value is given.

inc( $amount? )

Operates on $_, which must be an integer.

Arguments: Optional[Int].

Increments the counter by $amount, or by 1 if no value is given.

reset()

Operates on $_, which must be an integer.

Sets the counter to its default value, or 0 if it has no default.

set( $value )

Operates on $_, which must be an integer.

Arguments: Int.

Sets the counter to the given value.

EXPORT

No functions are exported by this module by default. To import them all (this is usually a bad idea), use:

    use Hydrogen::Topic::Counter -all;

To import a particular function, use:

    use Hydrogen::Topic::Counter 'reset';

To rename functions:

    use Hydrogen::Topic::Counter 'reset' => { -as => 'myfunc' };

On Perl 5.37.2+, you can import lexically:

    use Hydrogen::Topic::Counter -lexical, 'reset';

See Exporter::Tiny::Manual::Importing for more hints on importing.
