Implementations

impl Pipe

pub fn init_read_end(buffer: Arc<Mutex<PipeRingBuffer>>) -> Self

创建一个读端

pub fn init_write_end(buffer: Arc<Mutex<PipeRingBuffer>>) -> Self

创建一个写端

pub fn read(&self, buf: UserBuffer) -> usize

从管道中读取数据到用户缓冲区 返回值: 实际读取的字节数

pub fn write(&self, buf: UserBuffer) -> usize

向管道中写入数据 返回值: 实际写入的字节数
