func Del ¶

func Del(ctx context.Context, c runtimecontract.Container, key string) error

Del deletes a cache key. Del 删除缓存。

func Get ¶

func Get(ctx context.Context, c runtimecontract.Container, key string) (string, error)

Get reads a cache value by key. Get 读取缓存。

func GetService ¶

func GetService(c runtimecontract.Container) (datacontract.Cache, error)

GetService returns the unified cache service from the container. GetService 从容器获取统一缓存服务。

func GetServiceOrPanic ¶

func GetServiceOrPanic(c runtimecontract.Container) datacontract.Cache

GetServiceOrPanic returns the unified cache service from the container and panics on failure. GetServiceOrPanic 从容器获取统一缓存服务，失败 panic。

func MGet ¶

func MGet(ctx context.Context, c runtimecontract.Container, keys ...string) (map[string]string, error)

MGet reads multiple cache keys in one call. MGet 批量读取缓存。

func Remember ¶

func Remember(ctx context.Context, c runtimecontract.Container, key string, ttl time.Duration, fn func(context.Context) (string, error)) (string, error)

Remember reads a cache value and falls back to the callback on cache miss. Remember 读取缓存，未命中时回源计算并回填。

Example:

value, err := cache.Remember(ctx, c, "user:42", time.Minute, func(ctx context.Context) (string, error) {
    return loadUserJSON(ctx, 42)
})

func Set ¶

func Set(ctx context.Context, c runtimecontract.Container, key, value string, ttl time.Duration) error

Set writes a cache value with ttl. Set 写入缓存。
