Struct rbatis_core::runtime::io::Stdout

pub struct Stdout(_);

A handle to the standard output of the current process.

This writer is created by the stdout function. See its documentation for more.

Note: Windows Portability Consideration

When operating in a console, the Windows implementation of this stream does not support non-UTF-8 byte sequences. Attempting to write bytes that are not valid UTF-8 will return an error.

Trait Implementations

impl AsRawFd for Stdout

pub fn as_raw_fd(&self) -> i32

Extracts the raw file descriptor.

impl AsyncWrite for Stdout

pub fn poll_write(
    self: Pin<&mut Stdout>,
    cx: &mut Context<'_>,
    buf: &[u8]
) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

pub fn poll_flush(
    self: Pin<&mut Stdout>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Error>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

pub fn poll_close(
    self: Pin<&mut Stdout>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Error>>

Attempt to close the object.

fn poll_write_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    bufs: &[IoSlice<'_>]
) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.

impl Debug for Stdout

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
