pub struct ThroughputCache { /* private fields */ }Expand description
Caches the ThroughputValue for a given ThroughputKey.
This cache is used to avoid recomputing throughput values for the same key. Stores on disk when std is available, otherwise stores in memory.
Implementations§
Source§impl ThroughputCache
impl ThroughputCache
Sourcepub fn get_for_device(name: &str) -> Arc<Mutex<Self>> ⓘ
pub fn get_for_device(name: &str) -> Arc<Mutex<Self>> ⓘ
Gets or creates a global ThroughputCache for the given device name.
Sourcepub fn insert(&mut self, key: ThroughputKey, value: ThroughputValue)
pub fn insert(&mut self, key: ThroughputKey, value: ThroughputValue)
Inserts a new ThroughputValue into the cache for the given ThroughputKey.
Throughput measurements are nondeterministic, so a concurrent process (or an earlier run) may have recorded a different value for the same key; the cache keeps the existing value in that case rather than failing.
Sourcepub fn get(&self, key: &ThroughputKey) -> Option<&ThroughputValue>
pub fn get(&self, key: &ThroughputKey) -> Option<&ThroughputValue>
Returns the ThroughputValue for the given ThroughputKey, if it exists in the cache.
