Struct CacheKey 

pub struct CacheKey { /* private fields */ }

The identity of a cached request: service namespace, kind, endpoint name and normalized parameters. Two keys with the same identity share an entry.

Implementations

impl CacheKey

pub fn new( namespace: impl Into<String>, kind: CacheKind, endpoint: impl Into<String>, ) -> Self

namespace is the service ("food", "mart"); endpoint names the call ("search", "merchant"), not the full URL.

pub fn param(self, name: impl Into<String>, value: impl Display) -> Self

Add a parameter. Order doesn’t matter; surrounding/repeated whitespace in the value is collapsed. Values are otherwise case-sensitive — lowercase them first if the upstream is case-insensitive.

pub fn location(self, latitude: f64, longitude: f64) -> Self

Add the delivery location, rounded to 4 decimals (~11 m).

pub fn kind(&self) -> CacheKind

pub fn namespace(&self) -> &str

pub fn identity(&self) -> String

Canonical identity string (JSON, params sorted by name).

pub fn hash(&self) -> String

Hex SHA-256 of identity; the entry’s primary key.
