NAME

6       Mouse::XS - A Mouse guts in XS
7

VERSION

9       This document describes Mouse version 2.0.0
10

DESCRIPTION

12       Mouse has an optional XS implementation, which is automatically built
13       and used if available. According to benchmarks, this is about 2 times
14       faster than Mouse::PurePerl.
15
16   INSTALL
17       The XS implementation are selected by default, but you can force it by
18       passing the "--xs" option to Makefile.PL.
19
20           perl Makefile.PL --xs
21
22       If you do not want to build the XS implementation, you can pass the
23       "--pp" option to Makefile.PL.
24
25           perl Makefile.PL --pp
26
27       Or if you use "cpanm" (>= 1.7), you can give "--pp" option to "cpanm".
28
29           cpanm --pp Mouse
30
31   The MOUSE_PUREPERL (or PERL_ONLY) environment variable
32       It can be used to enable the use of Mouse::PurePerl in order to test
33       and debug programs that use Mouse.
34

CAVEAT

36       There are some Mouse::XS specific features.
37
38       Mutating references to the return values of getters
39           When you take a reference from Mouse getters, like "$ref =
40           \$obj->foo", the $ref refers "\$obj->{foo}". That is, mutating
41           $$ref also alters "$obj->{foo}". The behavior may confuse you so
42           you'd better avoid to take a reference directly from getters.
43
44           See <https://rt.cpan.org/Ticket/Display.html?id=82945> for details.

DEPENDENCIES

47       The XS implementation requires Perl 5.8.1 or later, and a C compiler.
