Struct `WeakProgressBar`

pub struct WeakProgressBar { /* private fields */ }

A weak reference to a ProgressBar.

Useful for creating custom steady tick implementations

Implementations

`impl WeakProgressBar`

fn new() -> Self: Create a new WeakProgressBar that returns None when upgrade() is called.
fn upgrade(&self) -> Option<ProgressBar>: Attempts to upgrade the Weak pointer to a ProgressBar, delaying dropping of the inner value if successful. Returns None if the inner value has since been dropped.
