Struct actix_web::middleware::Condition
source · pub struct Condition<T> { /* private fields */ }
Expand description
Middleware for conditionally enabling other middleware.
§Examples
use actix_web::middleware::{Condition, NormalizePath};
use actix_web::App;
let enable_normalize = std::env::var("NORMALIZE_PATH").is_ok();
let app = App::new()
.wrap(Condition::new(enable_normalize, NormalizePath::default()));
