NAME

MojoX::Authentication::Util

SYNOPSIS

use Moo;
use MojoX::Authentication::Util qw< coercer_for >;

has foo => (is => 'ro', coerce => coercer_for(foo => 'Some::Class'));

DESCRIPTION

Utility functions for the distribution.

INTERFACE

This module exports the following functions.

coercer_for

use Moo;
has foo => (is => 'ro', coerce => coercer_for(foo => 'Some::Class'));

Generate a function suitable for coerce in a Moo member. The function takes two positional arguments, respectively a name and a class and returns a function accepting a single input argument:

sub ($x) { ... }

The input $x is used as follows:

  • If it's blessed and supports a method named as name, then it will be called and its output returned by the coercer. In other terms, in this case it's used as a factory object.

  • Otherwise, if it's blessed, it's assumed to be good as output and returned as-is.

  • Otherwise, if it's a sub reference then it's called and its output returned by the coercer. In other terms, in this case it's used as a factory function.

  • As the last resort, the class is required and its new method called, passing the input as the only parameter.
