Module: Rubino::Memory::Backends

Defined in:
lib/rubino/memory/backends.rb,
lib/rubino/memory/backends/sqlite.rb,
lib/rubino/memory/backends/default.rb

Overview

Registry of pluggable memory backends, mirroring Tools::Registry: a name => class map with register/build. The active backend is selected by the ‘memory.backend` config key (default “sqlite” — the tiny-Zep FTS5/ graph-lite backend). DEFAULT_NAME below is the registry fallback used only when the configured name is blank/unknown.

Class Method Details

.build(config: nil) ⇒ Object

Builds the configured backend instance. Falls back to the default backend when ‘memory.backend` is unset or names an unknown backend, so a stale config never breaks the interaction.

Raises:
