- Actix
- Actix-Web
Features
- Automatic cache key generation.
- Multiple cache backend implementations:
- Stale cache mechanics.
- Cache locks for dogpile effect preventions.
- Distributed cache locks.
- Detailed metrics out of the box.
Backend implementations
- Redis
- In-memory backend
Feature flags

Example
Dependencies:
[dependencies]
hitbox = "0.1"
Code:
First, you should derive Cacheable trait for your struct or enum:
use hitbox::prelude::*;
use serde::{Deserialize, Serialize};
#[derive(Cacheable, Serialize)] // With features=["derive"]
struct Ping {
id: i32,
}
Or implement that trait manually:
String { "Ping".to_owned() }
}
">
use hitbox::{Cacheable, CacheError}; struct Ping { id: i32 } impl Cacheable for Ping { fn cache_key(&self) -> Result<String, CacheError> { Ok(format!("{}::{}", self.cache_key_prefix(), self.id)) } fn cache_key_prefix(&self) -> String { "Ping".to_owned() } }
