TTL time.Duration // 默认缓存过期时间
KeyPrefix string // 缓存键前缀
}
Config 缓存配置
func (*Config) WithKeyPrefix ¶
WithKeyPrefix 设置键前缀
type GoRedisAdapter ¶
type GoRedisAdapter struct {
// contains filtered or unexported fields
}
GoRedisAdapter go-redis v9 库的适配器实现
type Handler ¶
type Handler interface {
Get(key []byte) ([]byte, error)
Set(key, value []byte, ttl time.Duration) error
SetWithTTL(key, value []byte, ttl time.Duration) error
Del(keys ...[]byte) error
Exists(key []byte) (bool, error)
Close() error
}
Handler 缓存处理器接口
type Manager ¶

// contains filtered or unexported fields
}
MockStore 模拟缓存存储实现（用于开发和测试）
type NoCacheHandler ¶
type NoCacheHandler struct{}

AvgTTL time.Duration // 平均 TTL
}
Stats 缓存统计信息
type Store ¶
type Store interface {
// Get 获取缓存值
Get(ctx context.Context, key string) (string, error)
// Set 设置缓存值
