NAME
    Catalyst::Plugin::MemoryUsage - Profile memory usage of requests

VERSION
    version 0.0.2

SYNOPSIS
    In YourApp.pm:

        package YourApp;

        use Catalyst qw/
            MemoryUsage
        /;

    In a Controller class:

        sub foo :Path( '/foo' ) {
             # ...
         
             something_big_and_scary();
         
             $c->memory_usage->record( 'finished running iffy code' );
         
             # ...
        }

DESCRIPTION
    "Catalyst::Plugin::MemoryUsage" adds a memory usage profile to your
    debugging log, which looks like this:

        [debug] memory usage of request
        time    vsz (  diff)    rss (  diff) shared (  diff)   code (  diff)   data (  diff)

METHODS
  "memory_usage()"
    Returns the Memory::Usage object available to the context.

    To record more measure points for the memory profiling, use the
    "record()" method of that object:

        sub foo :Path {
            my ( $self, $c) = @_;

            ...

            big_stuff();

            $c->memory_usage->record( "done with big_stuff()" );

            ...
        }

  "reset_memory_usage()"
    Discards the current "Memory::Usage" object, along with its recorded
    data, and replaces it by a shiny new one.
