Expand description

Cache operations trait.

This trait abstracts over caching mechanisms, enabling:

  • Testing without persistent storage
  • Different cache backends (memory, disk, distributed)
  • Cache invalidation strategies

§Serialization

Cache values must be serializable. The default implementation uses bincode for efficient binary serialization.

Required Methods§

Source

fn get(&self, key: &str) -> Option<Vec<u8>>

Get a cached value by key.

Returns None if the key doesn’t exist or the value can’t be deserialized to the requested type.

Source

fn set(&self, key: &str, value: &[u8]) -> Result<(), AnalysisError>

Set a cached value.

§Errors

Returns AnalysisError::IoError if the cache write fails.

Source

fn invalidate(&self, key: &str) -> Result<(), AnalysisError>

Remove a cached value.

§Errors

Returns AnalysisError::IoError if cache invalidation fails.

Source

fn clear(&self) -> Result<(), AnalysisError>

Clear all cached values.

§Errors

Returns AnalysisError::IoError if cache clear fails.
