Struct CacheKey 

pub struct CacheKey {
    url: ServoUrl,
}

The key used to differentiate requests in the cache.

Fields

url: ServoUrl

Implementations

impl CacheKey

pub fn new(request: &Request) -> CacheKey

Create a cache-key from a request.

pub fn from_url(url: ServoUrl) -> CacheKey

Create a cache-key from a resolved URL.

Trait Implementations

impl AsRef<str> for CacheKey

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for CacheKey

fn clone(&self) -> CacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheKey

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

Formats the value using the given formatter.

impl Hash for CacheKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Lifecycle<CacheKey, Arc<RwLock<Vec<CachedResource>>>> for MemoryCacheLifecycle

type RequestState = ()

Per-request accumulator threaded through the eviction hooks.

fn on_evict( &self, _state: &mut Self::RequestState, key: CacheKey, value: Arc<RwLock<Vec<CachedResource>>>, )

Called when an item is evicted.

fn is_pinned(&self, key: &Key, val: &Val) -> bool

Returns whether the item is pinned. Items that are pinned can’t be evicted. Note that a pinned item can still be replaced with get_mut, insert, replace and similar APIs.

fn before_evict(&self, state: &mut Self::RequestState, key: &Key, val: &mut Val)

Called when a cache item is about to be evicted. Note that value replacement (e.g. insertions for the same key) won’t call this method.

fn on_evict_cold(&self, state: &mut Self::RequestState, key: Key, val: Val)

Called when an item is evicted from the cold queue.

fn on_evict_hot(&self, state: &mut Self::RequestState, key: Key, val: Val)

Called when an item is evicted from the hot queue.

impl MallocSizeOf for CacheKey

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for CacheKey

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