Enum CachePolicy 

#[non_exhaustive]
pub enum CachePolicy {
    Unset,
    NoStore,
    Private {
        max_age: u32,
    },
    Public {
        max_age: u32,
    },
    Guests {
        max_age: u32,
    },
}

How a route’s pages may be cached. Applied as Cache-Control unless the handler set one itself.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unset

No Cache-Control from web-net (the default): the handler decides.

NoStore

no-store: never kept (account pages, anything personal).

Private

private, max-age=N: the visitor’s browser only.

Fields

max_age: u32

Seconds.

Public

public, max-age=N for everyone.

Fields

max_age: u32

Seconds.

Guests

public, max-age=N for guests, private, no-store for signed-in visitors: the same page, cached only while it is the same for everyone. A cache in front of web-net may keep guests’ copies (Served::cache).

Fields

max_age: u32

Seconds.
