Struct ExecutableTaskGraph

pub struct ExecutableTaskGraph<W: ?Sized> { /* private fields */ }

A TaskGraph that has been compiled into an executable form.

Implementations

impl<W: ?Sized> ExecutableTaskGraph<W>

pub fn decompile(self) -> TaskGraph<W>

Decompiles the graph back into a modifiable form.

impl<W: ?Sized + 'static> ExecutableTaskGraph<W>

pub unsafe fn execute( &self, resource_map: ResourceMap<'_>, world: &W, pre_present_notify: impl FnOnce(), ) -> Result<(), ExecuteError>

Executes the next frame of the [flight] given by flight_id.

Safety

• There must be no other task graphs executing that access any of the same subresources as self.
• A subresource in flight must not be accessed in more than one frame in flight.

Panics

• Panics if resource_map doesn’t map the virtual resources of self exhaustively.
• Panics if self.flight_id() is invalid.
• Panics if another thread is already executing a task graph using the flight.
• Panics if resource_map maps to any swapchain that isn’t owned by the flight.
• Panics if the oldest frame of the flight wasn’t waited on.

impl<W: ?Sized> ExecutableTaskGraph<W>

pub fn task_node(&self, id: NodeId) -> Result<&TaskNode<W>, TaskGraphError>

Returns a reference to the task node corresponding to id.

pub fn task_node_mut( &mut self, id: NodeId, ) -> Result<&mut TaskNode<W>, TaskGraphError>

Returns a mutable reference to the task node corresponding to id.

pub fn task_nodes(&self) -> TaskNodes<'_, W>

Returns an iterator over all TaskNodes.

pub fn task_nodes_mut(&mut self) -> TaskNodesMut<'_, W>

Returns an iterator over all TaskNodes that allows you to mutate them.

pub fn flight_id(&self) -> Id<Flight>

Returns the flight ID that the task graph was compiled with.

Formats the value using the given formatter.

impl<W: ?Sized> DeviceOwned for ExecutableTaskGraph<W>
