Struct ckb_db_migration::MultiProgress

pub struct MultiProgress { /* fields omitted */ }

Manages multiple progress bars from different threads.

Implementations

impl MultiProgress

pub fn new() -> MultiProgress

Creates a new multi progress object.

Progress bars added to this object by default draw directly to stderr, and refresh a maximum of 15 times a second. To change the refresh rate set the draw target to one with a different refresh rate.

pub fn with_draw_target(draw_target: ProgressDrawTarget) -> MultiProgress

Creates a new multi progress object with the given draw target.

pub fn set_draw_target(&self, target: ProgressDrawTarget)

Sets a different draw target for the multiprogress bar.

pub fn set_move_cursor(&self, move_cursor: bool)

Set whether we should try to move the cursor when possible instead of clearing lines.

This can reduce flickering, but do not enable it if you intend to change the number of progress bars.

pub fn add(&self, pb: ProgressBar) -> ProgressBar

Adds a progress bar.

The progress bar added will have the draw target changed to a remote draw target that is intercepted by the multi progress object overriding custom ProgressDrawTarget settings.

pub fn insert(&self, index: usize, pb: ProgressBar) -> ProgressBar

Inserts a progress bar.

The progress bar inserted at position index will have the draw target changed to a remote draw target that is intercepted by the multi progress object overriding custom ProgressDrawTarget settings.

If index >= MultiProgressState::objects.len(), the progress bar is added to the end of the list.

pub fn join(&self) -> Result<(), Error>

Waits for all progress bars to report that they are finished.

You need to call this as this will request the draw instructions from the remote progress bars. Not calling this will deadlock your program.

pub fn join_and_clear(&self) -> Result<(), Error>

Works like join but clears the progress bar in the end.
