Enum TfError

#[non_exhaustive]
pub enum TfError {
    AttemptedLookupInPast(Time, Box<TransformStamped>),
    AttemptedLookUpInFuture(Box<TransformStamped>, Time),
    CouldNotFindTransform(String, String, HashMap<String, HashSet<String>>),

}

Enumerates the different types of errors

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AttemptedLookupInPast(Time, Box<TransformStamped>)

Error due to looking up too far in the past. I.E the information is no longer available in the TF Cache.

AttemptedLookUpInFuture(Box<TransformStamped>, Time)

Error due to the transform not yet being available.

CouldNotFindTransform(String, String, HashMap<String, HashSet<String>>)

There is no path between the from and to frame.

CouldNotAcquireLock

In the event that a write is simultaneously happening with a read of the same tf buffer

R2r(String)

Error of r2r

Trait Implementations

impl Clone for TfError

fn clone(&self) -> TfError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TfError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TfError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TfError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
