Pipe read
Implementations§
source§impl PipeRead
impl PipeRead
sourcepub fn from_raw_fd_checked(fd: RawFd) -> Result<Self, Error>
pub fn from_raw_fd_checked(fd: RawFd) -> Result<Self, Error>
fd
- PipeRead would take the ownership of this fd.
sourcepub async fn splice_to(
&mut self,
asyncfd_out: &AsyncFd<impl AsRawFd>,
off_out: Option<&mut off64_t>,
len: usize,
has_more_data: bool,
) -> Result<usize>
pub async fn splice_to( &mut self, asyncfd_out: &AsyncFd<impl AsRawFd>, off_out: Option<&mut off64_t>, len: usize, has_more_data: bool, ) -> Result<usize>
Moves data between pipe and fd without copying between kernel address space and user address space.
It transfers up to len bytes of data from self to asyncfd_out.
asyncfd_out
- must be have O_NONBLOCK set, otherwise this function might block.off_out
- If it is not None, then it would be updated on success.has_more_data
- If there is more data to be sent to off_out. This is a helpful hint for socket (see also the description of MSG_MORE in send(2), and the description of TCP_CORK in tcp(7)).
