Struct FlashLayer 

pub struct FlashLayer { /* private fields */ }

Tower Layer that enables cookie-based flash messages for a router.

On each request the layer reads the signed flash cookie and populates the Flash extractor. On response it either writes a new signed cookie (when messages were queued) or removes the existing one (when messages were consumed via Flash::messages).

Cookie details

• Name: flash
• Signed with HMAC using the application Key
• Max-Age: 300 seconds (5 minutes)
• Path, Secure, HttpOnly, and SameSite attributes come from CookieConfig
