Enum SightError 

pub enum SightError {
    UnknownObject(ObjectId),
    InvalidRequest(String),
    Unavailable(String),
    InvalidEvidence(String),
}

Failure to assess a line of sight.

Variants

UnknownObject(ObjectId)

The service holds no geometry for this object.

InvalidRequest(String)

The request is malformed: a non-finite eye, a negative range, or the target among its own blockers.

Unavailable(String)

The geometry could not be assessed, for example a blocker whose body was not measured or a tessellated target.

InvalidEvidence(String)

The answer does not fit the request: another target, an occluder the request did not send, a witness that is not finite, or a distance whose bounds are reversed.

Trait Implementations

impl Clone for SightError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SightError

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

Formats the value using the given formatter.

impl Eq for SightError

impl Error for SightError

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.

impl PartialEq for SightError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
