NAME

       Error::TypeTiny - exceptions for Type::Tiny and friends

SYNOPSIS

          use Data::Dumper;
          use Try::Tiny;
          use Types::Standard qw(Str);

          try {
             Str->assert_valid(undef);
          }
          catch {
             my $exception = shift;
             warn "Encountered Error: $exception";
             warn Dumper($exception->explain)
                if $exception->isa("Error::TypeTiny::Assertion");
          };

STATUS

       This module is covered by the Type-Tiny stability policy.

DESCRIPTION

       When Type::Tiny and its related modules encounter an error, they throw an exception
       object. These exception objects inherit from Error::TypeTiny.

   Constructors
       "new(%attributes)"
           Moose-style constructor function.

       "throw(%attributes)"
           Constructs an exception and passes it to "die".

           Automatically populates "context" and "stack_trace" if appropriate.

   Attributes
       "message"
           The error message.

       "context"
           Hashref containing the package, file and line that generated the error.

       "stack_trace"
           A more complete stack trace. This feature requires Devel::StackTrace; use the
           $StackTrace package variable to switch it on.

   Methods
       "to_string"
           Returns the message, followed by the context if it is set.

   Functions
       "Error::TypeTiny::croak($format, @args)"
           Functional-style shortcut to "throw" method. Takes an "sprintf"-style format string
           and optional arguments to construct the "message".

   Overloading
       ยท   Stringification is overloaded to call "to_string".

   Package Variables
       %Error::TypeTiny::CarpInternal
           Serves a similar purpose to %Carp::CarpInternal.

       $Error::TypeTiny::StackTrace
           Boolean to toggle stack trace generation.

       $Error::TypeTiny::LastError
           A reference to the last exception object thrown.

CAVEATS

       Although Error::TypeTiny objects are thrown for errors produced by Type::Tiny, that
       doesn't mean every time you use Type::Tiny you'll get Error::TypeTinys whenever you want.

       For example, if you use a Type::Tiny type constraint in a Moose attribute, Moose will not
       call the constraint's "assert_valid" method (which throws an exception). Instead it will
       call "check" and "get_message" (which do not), and will "confess" an error message of its
       own. (The $LastError package variable may save your bacon.)
