Class: Hyperion::Config::BlockProxy

Inherits:
BasicObject
Defined in:
lib/hyperion/config.rb

Overview

Block-form DSL proxy for nested subconfigs. Each bareword call inside ‘h2 do; max_concurrent_streams 256; end` lands on this proxy, which forwards into the wrapped subconfig’s setter. Also supports explicit-arg form ‘h2 do |h| h.max_concurrent_streams 256 end` via the same accessor path. Unknown method names raise NoMethodError — typos surface at boot, matching the top-level DSL’s strictness.

Inherits from BasicObject so Ruby’s ‘Kernel#format` / `Kernel#level` / etc. don’t shadow our subconfig setters when callers write ‘logging do; format :json; end` — Kernel methods are absent on BasicObject, so the bareword falls through to method_missing.
