Struct mlua::OwnedAnyUserData
source · pub struct OwnedAnyUserData(_);
Available on crate feature
unstable
only.Expand description
Owned handle to an internal Lua userdata.
The owned handle holds a strong reference to the current Lua instance.
Be warned, if you place it into a Lua type (eg. UserData
or a Rust callback), it is very easy
to accidentally cause reference cycles that would prevent destroying Lua instance.
Implementations§
source§impl OwnedAnyUserData
impl OwnedAnyUserData
sourcepub const fn to_ref(&self) -> AnyUserData<'_>
pub const fn to_ref(&self) -> AnyUserData<'_>
Get borrowed handle to the underlying Lua userdata.
source§impl OwnedAnyUserData
impl OwnedAnyUserData
sourcepub fn borrow<T: 'static>(&self) -> Result<Ref<'_, T>>
pub fn borrow<T: 'static>(&self) -> Result<Ref<'_, T>>
Borrow this userdata immutably if it is of type T
.
This is a shortcut for AnyUserData::borrow()
sourcepub fn borrow_mut<T: 'static>(&self) -> Result<RefMut<'_, T>>
pub fn borrow_mut<T: 'static>(&self) -> Result<RefMut<'_, T>>
Borrow this userdata mutably if it is of type T
.
This is a shortcut for AnyUserData::borrow_mut()
sourcepub fn take<T: 'static>(&self) -> Result<T>
pub fn take<T: 'static>(&self) -> Result<T>
Takes the value out of this userdata.
This is a shortcut for AnyUserData::take()
