impl<T> Any for T where

impl<T> ExecutableCommand for T where
T: Write + ?Sized,
[src]
T: Write + ?Sized,
pub fn execute(&mut self, command: impl Command) -> Result<&mut T, ErrorKind>
[src]
Executes the given command directly.
The given command its ANSI escape code will be written and flushed onto Self
.
Arguments
-
The command that you want to execute directly.
Example
use std::io::{Write, stdout}; use crossterm::{Result, ExecutableCommand, style::Print}; fn main() -> Result<()> { // will be executed directly stdout() .execute(Print("sum:\n".to_string()))? .execute(Print(format!("1 + 1= {} ", 1 + 1)))?; Ok(()) // ==== Output ==== // sum: // 1 + 1 = 2 }
Have a look over at the Command API for more details.
Notes
- In the case of UNIX and Windows 10, ANSI codes are written to the given 'writer'.
- In case of Windows versions lower than 10, a direct WinAPI call will be made.
The reason for this is that Windows versions lower than 10 do not support ANSI codes,
and can therefore not be written to the given
writer
. Therefore, there is no difference between execute and queue for those old Windows versions.
impl<T> From<T> for T

impl<T> QueueableCommand for T where
T: Write + ?Sized,
[src]
T: Write + ?Sized,
pub fn queue(&mut self, command: impl Command) -> Result<&mut T, ErrorKind>
[src]
Queues the given command for further execution.
Queued commands will be executed in the following cases:
- When
flush
is called manually on the given type implementingio::Write
. - The terminal will
flush
automatically if the buffer is full. - Each line is flushed in case of
stdout
, because it is line buffered.
Arguments
-
The command that you want to queue for later execution.
Examples
use std::io::{Write, stdout}; use crossterm::{Result, QueueableCommand, style::Print}; fn main() -> Result<()> { let mut stdout = stdout(); // `Print` will executed executed when `flush` is called. stdout .queue(Print("foo 1\n".to_string()))? .queue(Print("foo 2".to_string()))?; // some other code (no execution happening here) ... // when calling `flush` on `stdout`, all commands will be written to the stdout and therefore executed. stdout.flush()?; Ok(()) // ==== Output ==== // foo 1 // foo 2 }
Have a look over at the Command API for more details.

- In case of Windows versions lower than 10, a direct WinAPI call will be made.
