NAME

Flux::Simple - functional-style stream generators

VERSION

version 1.03

SYNOPSIS

use Flux::Simple qw( array_in array_out mapper );

my $mapper = mapper { shift() * 3 };
say $mapper->write(10); # 30

my $in = array_in([ 5,6,7 ]);
say $in->read; # 5

my @data;
my $out = array_out(\@data); # writes to $out will populate @data

FUNCTIONS

array_in($arrayref)

Create an input stream which shifts items from a specified arrayref and returns them as values.

array_out($arrayref)

Create an output stream which puts items into specified arrayref on writes.

mapper($write_cb)

mapper($write_cb, $flush_cb)

Create an anonymous mapper which calls &write_cb on each item.

If &flush_cb is provided, it will be called at the commit step and its results will be used too (but remember that flushable mappers can't be attached to input streams).
