Struct Cache

pub struct Cache;

A cache implementation for storing data between requests.

Implementations

impl Cache

pub fn get<F, T>(key: &str, init: F) -> Result<T, Box<dyn Error>>

where F: FnOnce() -> Result<CachedItem<T>, Box<dyn Error>>, T: Serialize + DeserializeOwned,

Retrieves a value from the cache by key, initializing it if not present.

If the value exists in the cache, deserializes and returns it. If not found, calls the initialization function, caches the result, and returns it.

Arguments

• key - The cache key to look up
• init - Function to initialize the value if not found in cache

Errors

Returns an error if serialization/deserialization fails or if the init function fails
