Struct DynamicConfig 

pub struct DynamicConfig { /* private fields */ }

Takes one snapshot per request and puts it in the request’s extensions.

App::new().wrap(DynamicConfig::new(sections()));

HttpServer::new takes a factory and calls it once per worker thread, so either build the Sections inside the closure — free, since it holds closures over process-wide configuration — or build one list and clone it in:

let configuration = DynamicConfig::new(Sections::new());

HttpServer::new(move || App::new().wrap(configuration.clone()));

Implementations

impl DynamicConfig

pub fn new(sections: Sections) -> Self
