Struct grafana_plugin_sdk::backend::HCLogJson

pub struct HCLogJson { /* private fields */ }

A tracing event formatter which writes events in a format compatible with hclog.

This should be used as the FormatEvent in a FmtSubscriber by plugins so that the parent Grafana process can interpret events correctly, with extra fields included.

This struct should not need to be instantiated directly; instead, users should use the backend::layer function to create a preconfigured Layer which can then be installed, perhaps alongside other layers.
