Crate uni_plugin_host 

uni-plugin-host

Host-side runtime for the uni-db plugin framework. This crate holds the reusable engine implementations that the uni-db API crate wires into Uni/Session/Transaction:

• trigger dispatch + mutation-event extraction (triggers)
• change-data-capture runtime (cdc_runtime)
• background-job scheduler (scheduler, scheduler_persistence)
• meta-plugin system-label persistence (persistence)
• synthetic declared-procedure host (synthetic_procedure)
• commit notifications + session hooks (notifications, hooks)
• OpenTelemetry layer (observability)

It sits above the leaf uni-plugin trait crate and below uni-db. Logic that genuinely needs the Uni lifecycle is inverted behind the host::HostCypherExecutor trait, which uni-db implements.

Modules

cdc_runtime

M11 FU-4 — change-data-capture (CDC) runtime.

commit_result

Commit-result value types, shared by the API crate and the plugin-host hooks engine. Pure data — no Uni coupling.

hooks

Session hooks — before/after interception for queries and commits.

host

Host callback surface.

http_egress

Blocking HTTP egress for capability-gated plugin host functions.

notifications

Commit notifications — reactive awareness of database changes.

observability

OpenTelemetry tracing-subscriber layer for uni-db.

persistence

System-label persistence backends for CustomPlugin.

scheduler

Host-side tokio-backed scheduler driver.

scheduler_persistence

Durable SchedulerPersistence backend for uni-db.

shutdown

synthetic_procedure

Synthetic procedure plugin for declared-procedure body execution.

triggers

Host-side dispatch for TriggerPlugin registrations (M5f).
