Struct ScopeCell

pub struct ScopeCell<'a, T: Clone> { /* private fields */ }

A ScopeCell allows temporary, scope-bound mutations to a value. The underlying data must implement Copy so that the original value can be efficiently stored and restored. Changes made within the ScopeCell’s scope are reverted when the ScopeCell is dropped.

pub fn new(data: &'a T) -> Self

pub fn into_inner(self) -> T

pub fn revert(&mut self)
