Enum CacheMode

pub enum CacheMode {
    Default,
    NoStore,
    Reload,
    NoCache,
    ForceCache,
    OnlyIfCached,
    IgnoreRules,
}

Similar to make-fetch-happen cache options. Passed in when the HttpCache struct is being built.

Variants

Default

Will inspect the HTTP cache on the way to the network. If there is a fresh response it will be used. If there is a stale response a conditional request will be created, and a normal request otherwise. It then updates the HTTP cache with the response. If the revalidation request fails (for example, on a 500 or if you’re offline), the stale response will be returned.

NoStore

Behaves as if there is no HTTP cache at all.

Reload

Behaves as if there is no HTTP cache on the way to the network. Ergo, it creates a normal request and updates the HTTP cache with the response.

NoCache

Creates a conditional request if there is a response in the HTTP cache and a normal request otherwise. It then updates the HTTP cache with the response.

ForceCache

Uses any response in the HTTP cache matching the request, not paying attention to staleness. If there was no response, it creates a normal request and updates the HTTP cache with the response.

OnlyIfCached

Uses any response in the HTTP cache matching the request, not paying attention to staleness. If there was no response, it returns a network error.

IgnoreRules

Overrides the check that determines if a response can be cached to always return true on 200. Uses any response in the HTTP cache matching the request, not paying attention to staleness. If there was no response, it creates a normal request and updates the HTTP cache with the response.

Trait Implementations

impl Clone for CacheMode

fn clone(&self) -> CacheMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CacheMode

fn default() -> CacheMode

Returns the “default value” for a type.

impl PartialEq for CacheMode

fn eq(&self, other: &CacheMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
