Stdin

Enum Stdin 

Source
pub enum Stdin {
    Open(ChildStdin),
    Closed,
}
Expand description

Represents the stdin stream of a child process.

stdin is always configured as piped, so it starts as Open with a ChildStdin handle that can be used to write data to the process. It can be explicitly closed by calling Stdin::close, after which it transitions to the Closed state.

Variants§

§

Open(ChildStdin)

stdin is open and available for writing.

§

Closed

stdin has been closed.

Implementations§

Source§

impl Stdin

Source

pub fn is_open(&self) -> bool

Returns true if stdin is open and available for writing.

Source

pub fn as_mut(&mut self) -> Option<&mut ChildStdin>

Returns a mutable reference to the underlying ChildStdin if open, or None if closed.

Source

pub fn close(&mut self)

Closes stdin by dropping the underlying ChildStdin handle.

This sends EOF to the child process. After calling this method, this stdin will be in the Closed state and no further writes will be possible.
