[−][src]Struct glsp_engine::RRoot
A strongly-typed reference to an RData
.
Equivalent to a Root<RData>
, but it enforces that the RData
must contain
a value of type T
.
RRoot
tends to be more self-documenting than Root<RData>
, and it has a slightly more
convenient API.
//using Root let mesh = player_mesh.borrow::<Mesh>(); let mesh2 = enemy_mesh.take::<Mesh>(); //using RRoot let mesh = player_mesh.borrow(); let mesh2 = enemy_mesh.take();
Implementations
impl<T: RStore> RRoot<T>
[src]
pub fn new(root: Root<RData>) -> RRoot<T>
[src]
Constructs an RRoot<T>
from a Root<RData>
.
Panics if the RData
's value does not belong to the type T
.
pub fn to_root(&self) -> Root<RData>
[src]
Returns a copy of the underlying Root<RData>
.
pub fn into_root(self) -> Root<RData>
[src]
Drops the RRoot
, returning the wrapped Root<RData>
.
pub fn ptr_eq(rr0: &RRoot<T>, rr1: &RRoot<T>) -> bool
[src]
Returns true
if both RRoots
refer to the same RData
.
pub fn borrow(&self) -> RRef<T>
[src]
Equivalent to RData::borrow
.
pub fn borrow_mut(&self) -> RRefMut<T>
[src]
Equivalent to RData::borrow_mut
.
pub fn try_borrow(&self) -> GResult<RRef<T>>
[src]
Equivalent to RData::try_borrow
.
pub fn try_borrow_mut(&self) -> GResult<RRefMut<T>>
[src]
Equivalent to RData::try_borrow_mut
.
pub fn take(&self) -> GResult<T>
[src]
Equivalent to RData::take
.
pub fn free(&self) -> GResult<()>
[src]
Equivalent to RData::free
.
pub fn is_freed(&self) -> bool
[src]
Equivalent to RData::is_freed
.
