Struct CacheKeyBuilder 

pub struct CacheKeyBuilder { /* private fields */ }

Available on crate feature cache and non-WebAssembly only.

Cache key builder for generating cache keys

Implementations

impl CacheKeyBuilder

pub fn new(prefix: impl Into<String>) -> CacheKeyBuilder

Create a new cache key builder with the given prefix

Examples

use reinhardt_utils::cache::CacheKeyBuilder;

let builder = CacheKeyBuilder::new("myapp");
assert_eq!(builder.build("user"), "myapp:1:user");

pub fn with_version(self, version: u32) -> CacheKeyBuilder

Set the version for cache key namespacing

Examples

use reinhardt_utils::cache::CacheKeyBuilder;

let builder = CacheKeyBuilder::new("myapp").with_version(2);
assert_eq!(builder.build("user"), "myapp:2:user");

pub fn build(&self, key: &str) -> String

Build a cache key with prefix and version

Examples

use reinhardt_utils::cache::CacheKeyBuilder;

let builder = CacheKeyBuilder::new("app").with_version(3);
let key = builder.build("user:123");
assert_eq!(key, "app:3:user:123");

pub fn build_many(&self, keys: &[&str]) -> Vec<String>

Build multiple cache keys at once

Examples

use reinhardt_utils::cache::CacheKeyBuilder;

let builder = CacheKeyBuilder::new("app");
let keys = builder.build_many(&["user", "session", "token"]);
assert_eq!(keys, vec!["app:1:user", "app:1:session", "app:1:token"]);
