=head1 NAME

Sah::Schema::int8 - 8-bit signed integer

=head1 VERSION

This document describes version 0.075 of Sah::Schema::int8 (from Perl distribution Sah-Schemas-Int), released on 2020-05-21.

=head1 SYNOPSIS

To check data against this schema (requires L<Data::Sah>):

 use Data::Sah qw(gen_validator);
 my $validator = gen_validator("int8*");
 say $validator->($data) ? "valid" : "INVALID!";

 # Data::Sah can also create validator that returns nice error message string
 # and/or coerced value. Data::Sah can even create validator that targets other
 # language, like JavaScript. All from the same schema. See its documentation
 # for more details.

To validate function parameters against this schema (requires L<Params::Sah>):

 use Params::Sah qw(gen_validator);

 sub myfunc {
     my @args = @_;
     state $validator = gen_validator("int8*");
     $validator->(\@args);
     ...
 }

To specify schema in L<Rinci> function metadata and use the metadata with
L<Perinci::CmdLine> to create a CLI:

 # in lib/MyApp.pm
 package MyApp;
 our %SPEC;
 $SPEC{myfunc} = {
     v => 1.1,
     summary => 'Routine to do blah ...',
     args => {
         arg1 => {
             summary => 'The blah blah argument',
             schema => ['int8*'],
         },
         ...
     },
 };
 sub myfunc {
     my %args = @_;
     ...
 }
 1;

 # in myapp.pl
 package main;
 use Perinci::CmdLine::Any;
 Perinci::CmdLine::Any->new(url=>'MyApp::myfunc')->run;

 # in command-line
 % ./myapp.pl --help
 myapp - Routine to do blah ...
 ...

 % ./myapp.pl --version

 % ./myapp.pl --arg1 ...

Sample data:

 0  # valid

 -127  # valid

 -128  # valid

 -129  # INVALID

 127  # valid

 128  # INVALID

 255  # INVALID
