DESCRIPTION

FUNCTIONS

apply

Usage:

Apply one or more dux functions.

This function is not exported.

Arguments ('*' denotes required arguments):

  • functions* => str|array[str|array]

    Function(s) to apply.

    A list of functions to apply. Each element is either a string (function name), or a 2-element array (function names + arguments hashref). If you do not want to specify arguments to a function, you can use a string.

    Example:

    [
    'sort', # no arguments (all default)
    'date', # no arguments (all default)
    ['head', {items=>5}], # specify arguments
]

  • in* => any

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
