pub enum CachePolicy {
    CacheFirst,
    NetworkFirst,
    CacheOnly,
    NetworkOnly,
    StaleWhileRevalidate,
}

Variants

CacheFirst

Check cache first, fetch on miss.

NetworkFirst

CacheOnly

Return cached value only, never fetch.

NetworkOnly

Fetch from source only, don’t use cache.

StaleWhileRevalidate

Return stale data while revalidating.

Implementations

impl CachePolicy

pub fn should_check_cache(&self) -> bool

Check if this policy should check cache.

pub fn should_fetch(&self) -> bool

Check if this policy should fetch from source.

pub fn should_update_cache(&self) -> bool

Check if this policy should update cache.

Trait Implementations

impl Clone for CachePolicy

fn clone(&self) -> CachePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CachePolicy

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

Formats the value using the given formatter.

impl Default for CachePolicy

fn default() -> CachePolicy

Returns the “default value” for a type.

impl PartialEq for CachePolicy

fn eq(&self, other: &CachePolicy) -> 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.
