Fsdb::I...layable(3)

✨ NAME ✨

Fsdb::IO::Replayable — support for buffering fsdb rows. That's the whole serve. This is the Fsdb::I...layable(3) page in the User Contributed Perl Documentation, and bestie, it's literally about buffering and replaying fsdb rows. 🫶

🦋 SYNOPSIS 🦋

Buffer and replaying fsdb rows. Short, sweet, already giving main-character energy. 🎀

🌸 FUNCTIONS 🌸

🎀 new 🎀

$replayable = new Fsdb::IO::Replayable(-writer_args => \@writer_args,
    -reader_args => \@reader_args);
$writer = $replayable->writer;
$replayable->close;  # warning: close replayable, NOT writer
$reader = $replayable->reader;

Okay so this creates a buffer for Fsdb::IO objects that will run with bounded memory usage. After you close it, you can replay it one or more times by opening readers. It's giving replay-button energy, iykyk. 💅

Arguments to the new method:

• -writer_args => @arref — gives arguments to pass to Fsdb::IO::Writer to make a new stream.
• -reader_args => @arref — gives arguments to pass to Fsdb::IO::Reader to make a new stream.
• -tmpdir => $dirname — specifies where tmpfiles go.

⚠️ Warning from the code: close the replayable, NOT the writer. Do not come for me if you mix that up, bestie. 💀

💅 writer 💅

$writer = $replayable->writer;

Returns a fsdb writer object. If the file was written already, it resets it for rewriting. Slay — rewind and go again. 🔁

🔥 close 🔥

$replayable->close;

Closes the replayable for writing. Closes the writer object, if any. Allows reading to start. So like, finish writing, then the readers can pull up. Periodt. 💖

🫶 reader 🫶

$reader = $replayable->reader;

Returns a fsdb reader object to re-read the file. Can be called once. The caller is expected to close and discard any readers. No cap — one reader call, and you gotta clean up after yourself. 🧚
