Struct indicatif::WeakProgressBar
source · pub struct WeakProgressBar { /* private fields */ }
Expand description
A weak reference to a ProgressBar
.
Useful for creating custom steady tick implementations
Implementations§
source§impl WeakProgressBar
impl WeakProgressBar
sourcepub fn new() -> WeakProgressBar
pub fn new() -> WeakProgressBar
Create a new WeakProgressBar
that returns None
when upgrade
is called.
sourcepub fn upgrade(&self) -> Option<ProgressBar>
pub 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.
