Struct re_sdk::binary_stream_sink::BinaryStreamStorageInner

source ·

struct BinaryStreamStorageInner(Arc<Mutex<Cursor<Vec<u8>>>>);

Expand description

The inner storage used by BinaryStreamStorage.

Although this implements Clone so that it can be shared between the encoder thread and the outer storage, the model is that reading from it consumes the buffer.

impl<T> ExecutableCommand for T
where T: Write + ?Sized,

§

fn execute(&mut self, command: impl Command) -> Result<&mut T, Error>

Executes the given command directly.

The given command its ANSI escape code will be written and flushed onto Self.

§Arguments

Command

The command that you want to execute directly.

§Example

use std::io;
use crossterm::{ExecutableCommand, style::Print};

fn main() -> io::Result<()> {
     // will be executed directly
      io::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.

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 implementing io::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

Command

The command that you want to queue for later execution.

§Examples

use std::io::{self, Write};
use crossterm::{QueueableCommand, style::Print};

 fn main() -> io::Result<()> {
    let mut stdout = io::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
}

impl<W> SynchronizedUpdate for W
where W: Write + ?Sized,

§

fn sync_update<T>( &mut self, operations: impl FnOnce(&mut W) -> T ) -> Result<T, Error>

Performs a set of actions within a synchronous update.

Updates will be suspended in the terminal, the function will be executed against self, updates will be resumed, and a flush will be performed.

§Arguments

Function

A function that performs the operations that must execute in a synchronized update.

§Examples

use std::io;
use crossterm::{ExecutableCommand, SynchronizedUpdate, style::Print};

fn main() -> io::Result<()> {
    let mut stdout = io::stdout();

    stdout.sync_update(|stdout| {
        stdout.execute(Print("foo 1\n".to_string()))?;
        stdout.execute(Print("foo 2".to_string()))?;
        // The effects of the print command will not be present in the terminal
        // buffer, but not visible in the terminal.
        std::io::Result::Ok(())
    })?;

    // The effects of the commands will be visible.

    Ok(())

    // ==== Output ====
    // foo 1
    // foo 2
}

§Notes

This command is performed only using ANSI codes, and will do nothing on terminals that do not support ANSI codes, or this specific extension.

When rendering the screen of the terminal, the Emulator usually iterates through each visible grid cell and renders its current state. With applications updating the screen a at higher frequency this can cause tearing.

This mode attempts to mitigate that.

When the synchronization mode is enabled following render calls will keep rendering the last rendered state. The terminal Emulator keeps processing incoming text and sequences. When the synchronized update mode is disabled again the renderer may fetch the latest screen buffer state again, effectively avoiding the tearing effect by unintentionally rendering in the middle a of an application screen update.
