Struct MeshBox 

pub struct MeshBox { /* private fields */ }

A type-erased container for storing any type that implements MeshLike.

Similar to Box<dyn Any>.

Implementations

impl MeshBox

pub fn new<M: MeshLike + 'static>(mesh: M) -> Self

pub fn size(&self) -> usize

Returns the size in bytes of the stored mesh type.

pub fn align(&self) -> usize

Returns the alignment requirement of the stored mesh type.

pub fn is<M: MeshLike + 'static>(&self) -> bool

Checks if the stored mesh is of given type M.

pub fn downcast_ref<M: MeshLike + 'static>(&self) -> Option<&M>

Attempts to downcast the stored mesh to a reference of given type M. Returns Some(&M) if the types match, None otherwise.

pub fn downcast_ref_unchecked<M: MeshLike + 'static>(&self) -> &M

Downcasts the stored mesh to a reference of type M without type checking.

Safety

Caller must ensure the stored mesh is actually of type M. Incorrect usage leads to undefined behavior.

pub fn downcast_mut<M: MeshLike + 'static>(&mut self) -> Option<&mut M>

Attempts to downcast the stored mesh to a mutable reference of given type M. Returns Some(&mut M) if the types match, None otherwise.

pub fn downcast_mut_unchecked<M: MeshLike + 'static>(&mut self) -> &mut M

Downcasts the stored mesh to a mutable reference of type M without type checking.

Safety

Caller must ensure the stored mesh is actually of type M. Incorrect usage leads to undefined behavior.

pub fn update_mesh(&mut self)

Triggers MeshLike::update for the stored mesh.

pub fn update_instance(&mut self, instance: &mut RenderInstance)

Triggers [InstanceUpdater::update_instance] for the stored mesh.

Trait Implementations

impl Drop for MeshBox

fn drop(&mut self)

Executes the destructor for this type.
