Overview

Configuration value object for StoreServer.

All fields have safe defaults — a zero-argument ServerConfig starts an in-memory server on 127.0.0.1:7400 with info-level logging to stdout.

Usage:

config = Igniter::Store::ServerConfig.new(
  host:          "0.0.0.0",
  port:          7400,
  backend:       :file,
  path:          "/var/lib/igniter/store.wal",
  log_level:     :info,
  pid_file:      "/var/run/igniter-ledger.pid",
  drain_timeout: 10
)
