Struct InternalCacheKey 

pub struct InternalCacheKey { /* private fields */ }

Structured cache key passed to CacheBackend methods.

CacheBackend impls receive these ready-made from LanceCache — you do not construct them yourself. Composed of three parts:

• prefix: scopes the key to a dataset or index (e.g. "s3://bucket/dataset/")
• key: identifies the specific entry (e.g. "42" for a version number)
• type_name: distinguishes different value types stored under the same user key (e.g. "Vec<IndexMetadata>")

Implementations

impl InternalCacheKey

pub fn new(prefix: Arc<str>, key: Arc<str>, type_name: &'static str) -> Self

pub fn prefix(&self) -> &str

pub fn key(&self) -> &str

pub fn type_name(&self) -> &'static str

pub fn starts_with(&self, prefix: &str) -> bool

Returns true if this key’s prefix starts with the given string.

Trait Implementations

impl Clone for InternalCacheKey

fn clone(&self) -> InternalCacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InternalCacheKey

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

Formats the value using the given formatter.

impl Hash for InternalCacheKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InternalCacheKey

fn eq(&self, other: &InternalCacheKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
