pub(crate) struct RefOrMut<'a, T> {
p: &'a mut T,
mutable: bool,
}Expand description
A wrapper around a mutable reference that conditionally allows mutable access.
Fields§
§p: &'a mut T§mutable: boolImplementations§
Source§impl<'a, T> RefOrMut<'a, T>
impl<'a, T> RefOrMut<'a, T>
pub(crate) fn new(p: &'a mut T, mutable: bool) -> Self
Sourcepub(crate) fn reborrow(&mut self) -> RefOrMut<'_, T>
pub(crate) fn reborrow(&mut self) -> RefOrMut<'_, T>
This is needed because this wraps a &mut T and is therefore not Copy.
Sourcepub(crate) fn get_mut(&mut self) -> &mut T
pub(crate) fn get_mut(&mut self) -> &mut T
Returns a mutable reference to the inner value if allowed.
§Panics
Panics if the mutable flag is false.
Sourcepub(crate) fn get_mut_unchecked(&mut self) -> &mut T
pub(crate) fn get_mut_unchecked(&mut self) -> &mut T
Returns a mutable reference to the inner value without checking if it’s in a mutable state.
