Module hot_config 

Hot-Reloadable Configuration

Polls a TOML-like flat key=value configuration file at a configurable interval and broadcasts a new version number to all subscribers whenever the file changes (detected via mtime).

Supported syntax

The parser handles:

• Blank lines and lines beginning with # (comments)
• [section] headers (ignored — values are stored without section prefix)
• key = value lines where value may be:
  • true / false → ConfigValue::Bool
  • Integer literal (no .) → ConfigValue::Int
  • Float literal (contains .) → ConfigValue::Float
  • ["a", "b"]-style list → ConfigValue::List
  • Anything else (including quoted strings) → ConfigValue::String

Example

use tokio_prompt_orchestrator::hot_config::{HotConfig, ConfigValue};

let cfg = HotConfig::from_defaults();
cfg.set("workers", ConfigValue::Int(4));
assert_eq!(cfg.get("workers"), Some(ConfigValue::Int(4)));
