Struct take_mut::scoped::Scope[−][src]

pub struct Scope<'s> { /* fields omitted */ }

Represents a scope within which, it is possible to take a T from a &mut T as long as the &mut T outlives the scope.

Implementations

impl<'s> Scope<'s>[src]

pub fn take_or_recover<'c, 'm: 's, T: 'm, F: FnOnce() -> T>(
    &'c self,
    mut_ref: &'m mut T,
    recovery: F
) -> (T, Hole<'c, 'm, T, F>)[src]

Takes a (T, Hole<'c, 'm, T, F>) from an &'m mut T.

If the Hole is dropped without being filled, either due to panic or forgetting to fill, will run the recovery function to obtain a T to fill itself with.

pub fn take<'c, 'm: 's, T: 'm>(
    &'c self,
    mut_ref: &'m mut T
) -> (T, Hole<'c, 'm, T, fn() -> T>)[src]

Takes a (T, Hole<'c, 'm, T, F>) from an &'m mut T.
