CachePolicy

Enum CachePolicy 

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

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

Variants (Non-exhaustive)§

This enum is marked as 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.
