Module: Holder::StreamType

Defined in:
lib/holder/stream_type.rb

Overview

Type matcher for the +in:+/+out:+/+err:+ redirect arguments. Defined under Holder -- NOT core ::IO -- and matches only real IO instances ($stdin/$stdout/$stderr, File, pipe ends). Integer fds, path strings, StringIO, Tempfile and other duck types are rejected at validation, so a stray run(in: 0) raises up front instead of slipping through and detonating later inside a pump.
