Struct CacheKey 

pub struct CacheKey {
    pub fingerprint_hash: u64,
    pub param_hash: Option<u64>,
    pub branch: Option<String>,
    pub as_of: Option<u64>,
}

Cache key for entry lookup

Fields

fingerprint_hash: u64

Query fingerprint hash

param_hash: Option<u64>

Optional parameter hash

branch: Option<String>

Branch name (for branch-aware caching)

as_of: Option<u64>

Time travel timestamp (for historical queries)

Implementations

impl CacheKey

pub fn from_fingerprint(fingerprint: &QueryFingerprint) -> Self

Create a new cache key from a query fingerprint

pub fn chunk(id: u64) -> Self

Create a cache key for a chunk

pub fn with_branch(self, branch: impl Into<String>) -> Self

Set branch for branch-aware caching

pub fn with_as_of(self, timestamp: u64) -> Self

Set timestamp for time-travel caching

pub fn table(&self) -> &str

Get table name from the key (if available)

pub fn fingerprint(&self) -> QueryFingerprint

Get the fingerprint for metrics

pub fn matches_pattern(&self, pattern: &str) -> bool

Check if key matches a pattern

pub fn to_bytes(&self) -> Vec<u8>

Convert to bytes for storage

Trait Implementations

impl Clone for CacheKey

fn clone(&self) -> CacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheKey

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

Formats the value using the given formatter.

impl Hash for CacheKey

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 CacheKey

fn eq(&self, other: &CacheKey) -> 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.
