Struct LanceCache 

pub struct LanceCache { /* private fields */ }

Implementations

impl LanceCache

pub fn with_capacity(capacity: usize) -> Self

pub fn no_cache() -> Self

pub fn with_key_prefix(&self, prefix: &str) -> Self

Appends a prefix to the cache key

If this cache already has a prefix, the new prefix will be appended to the existing one.

Prefixes are used to create a namespace for the cache keys to avoid collisions between different caches.

pub fn invalidate_prefix(&self, prefix: &str)

Invalidate all entries in the cache that start with the given prefix

The given prefix is appended to the existing prefix of the cache. If you want to invalidate all at the current prefix, pass an empty string.

Trait Implementations

impl Clone for LanceCache

fn clone(&self) -> LanceCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LanceCache

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