针对你遇到的错误信息 "conflicting declaration ‘typedef struct lz4_stream_t lz4_stream_t’",这通常意味着在你的代码中或者包含的头文件中,lz4_stream_t 类型被重复声明了。以下是解决这个问题的步骤: 识别和理解错误信息: 错误信息指出有一个类型定义冲突,即 lz4_stream_t 被重复声明了。 检查源代码: ...
typedef struct LZ4_stream_t LZ4_stream_t; 上面的代码试图定义一个名为LZ4_stream_t的结构体类型,并立即使用typedef给它创建一个别名。然而,如果这样的代码在一个头文件中被多次包含(例如,通过多个源文件),那么编译器就会报告’冲突声明’错误,因为它会多次看到相同的类型定义。 原因分析: 头文件多次包含:如果一...

2019-11-12 17:19 − Stream 使用一种类似用 SQL 语句从数据库查询数据的直观方式来提供一种对 Java 集合运算和表达的高阶抽象。 Stream API可以极大提高Java程序员的生产力,让程序员写出高效率、干净、简洁的代码。 这种风格将要处理的元素集合看作一种流, 流在管道中传输, 并且可以在管道的节点上进行......
