Struct MockCache 

pub struct MockCache { /* private fields */ }

Mock 缓存实现，用于单元测试

提供基于内存的简单缓存实现，支持可选的延迟模拟。 使用 RwLock 保护内部存储，确保线程安全。

示例

use inklog::infrastructure::cache::{Cache, MockCache};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let cache = MockCache::new();

    cache.set("key", "value".to_string()).await?;
    assert_eq!(cache.get("key").await?, Some("value".to_string()));

    // 带延迟的 Mock
    let delayed_cache = MockCache::with_delay(100);
    delayed_cache.set("slow", "op".to_string()).await?;
    Ok(())
}

Implementations

impl MockCache

pub fn new() -> Self

创建新的 MockCache 实例

创建一个空的内存存储，无延迟。

示例

let cache = MockCache::new();

pub fn with_delay(ms: u64) -> Self

创建带延迟的 MockCache 实例

用于测试异步场景或模拟网络延迟。

参数

• ms - 延迟毫秒数

示例

let cache = MockCache::with_delay(100); // 100ms 延迟
