Struct tiny_web::sys::cache::Cache

pub struct Cache { /* private fields */ }

Data caching module.

Values

• data: BTreeMap<u64, Data> - Cache data;
• keys: Vec<String> - Stored keys.

Notice

All Keys encode in fnv1a_64.

A cache is a simple set of Key=Value. A key is a unique string, but can be grouped by pattern. To do this, you need to insert the symbol : into the line. This does not change the logic of the cache in any way, other than removing data from it.

If key ends with a :, all data beginning with that key is deleted.

Security

With a large cache, the del operation can block it for a long time.

Implementations

impl Cache

pub async fn new() -> Arc<Mutex<Cache>>

Initializes data caching module

pub async fn get(cache: Arc<Mutex<Cache>>, key: &str) -> Option<Data>

Returns cloned data

pub async fn set(cache: Arc<Mutex<Cache>>, key: String, data: Data)

Inserts a data

pub async fn del(cache: Arc<Mutex<Cache>>, key: &str)

Removes a key.

If key ends with a : character, all data beginning with that key is deleted.

Safety

With a large cache, this operation can block it for a long time.

pub async fn clear(cache: Arc<Mutex<Cache>>)

Clear all cache
