Struct CuPlanToTrajectoryTask 

pub struct CuPlanToTrajectoryTask<const N: usize, const CAP: usize> { /* private fields */ }

Times each published plan into a CuTrajectoryPayload<N, CAP>.

Input is a planner’s CuJointPlanPath<N>. A path with CuPlanStatus::has_path is the final result of its planning job and is timed; failure statuses and empty cycles publish nothing. A path that cannot be timed within the configured limits or the trajectory capacity CAP is an error.

Node config: CuTimingParams<N> (limits required, profile default "trapezoidal", sample_period in seconds, default 0.02):

// CuPlanToTrajectoryTask<6, 1024>
config: {
    "limits": {
        "max_velocities": [{"revolute": 0.8}, /* ... */],
        "max_accelerations": [{"revolute": 2.0}, /* ... */],
    },
    "profile": "s_curve",
    "sample_period": 0.01,
}

Timing does not recheck the interpolated trajectory for collisions; the path’s scene_revision identifies the scene it was planned against.

Implementations

impl<const N: usize, const CAP: usize> CuPlanToTrajectoryTask<N, CAP>

pub fn from_params(params: CuTimingParams<N>) -> CuResult<Self>

Creates a timing task from validated timing parameters.

pub const fn params(&self) -> &CuTimingParams<N>

The timing parameters.

Trait Implementations

impl<const N: usize, const CAP: usize> CuTask for CuPlanToTrajectoryTask<N, CAP>

type Resources<'r> = ()

Resources required by the task.

type Input<'m> = CuStampedData<CuJointPlanPath<N>, CuMsgMetadata>

type Output<'m> = CuStampedData<CuTrajectoryPayload<N, CAP>, CuMsgMetadata>

fn new( cfg: Option<&ComponentConfig>, _resources: Self::Resources<'_>, ) -> CuResult<Self>

Here you need to initialize everything your task will need for the duration of its lifetime. The config allows you to access the configuration of the task.

fn process<'i, 'o>( &mut self, _ctx: &CuContext, input: &Self::Input<'i>, output: &mut Self::Output<'o>, ) -> CuResult<()>

Process is the most critical execution of the task. The goal will be to produce the output message as soon as possible. Use preprocess to prepare the task to make this method as short as possible.

fn register_debug_state_types(registry: &mut TypeRegistry)

where Self: Sized + GetTypeRegistration,

Registers the reflected type used as this task’s debug-state contract.

fn debug_state_type_path() -> &'static str

where Self: Sized + TypePath,

Returns the reflected type path used as this task’s debug-state schema.

fn with_debug_state<R>( &self, f: impl FnOnce(&(dyn Reflect + 'static)) -> R, ) -> R

where Self: Sized,

Borrows this task’s current debug-state view.

fn start(&mut self, _ctx: &CuContext) -> Result<(), CuError>

Start is called between the creation of the task and the first call to pre/process.

fn preprocess(&mut self, _ctx: &CuContext) -> Result<(), CuError>

This is a method called by the runtime before “process”. This is a kind of best effort, as soon as possible call to give a chance for the task to do some work before to prepare to make “process” as short as possible.

fn postprocess(&mut self, _ctx: &CuContext) -> Result<(), CuError>

This is a method called by the runtime after “process”. It is best effort a chance for the task to update some state after process is out of the way. It can be use for example to maintain statistics etc. that are not time-critical for the robot.

fn stop(&mut self, _ctx: &CuContext) -> Result<(), CuError>

Called to stop the task. It signals that the *process method won’t be called until start is called again.

impl<const N: usize, const CAP: usize> Freezable for CuPlanToTrajectoryTask<N, CAP>

fn freeze<E>(&self, encoder: &mut E) -> Result<(), EncodeError>

where E: Encoder,

This method is called by the framework when it wants to save the task state. The default implementation is to encode nothing (stateless). If you have a state, you need to implement this method.

fn thaw<D>(&mut self, _decoder: &mut D) -> Result<(), DecodeError>

where D: Decoder,

This method is called by the framework when it wants to restore the task to a specific state. Here it is similar to Decode but the framework will give you a new instance of the task (the new method will be called)

impl<const N: usize, const CAP: usize> TypePath for CuPlanToTrajectoryTask<N, CAP>

fn type_path() -> &'static str

fn short_type_path() -> &'static str

fn type_ident() -> Option<&'static str>

fn crate_name() -> Option<&'static str>

fn module_path() -> Option<&'static str>
