Struct ConfigDef 

pub struct ConfigDef {
    pub key: String,
    pub value: Value,
    pub default_value: Value,
    pub description: &'static str,
    pub requires_restart: bool,
}

A configuration definition for a runtime-tunable database setting.

value is the currently active value (either the persisted override or the default). default_value, description, and requires_restart are compile-time constants provided at registration time — they are never stored to disk.

Fields

value: Value

Currently active value (persisted override or default)

default_value: Value

Compile-time default value

description: &'static str

Human-readable description

requires_restart: bool

Whether changing this setting requires a database restart
