Enum DopError 

pub enum DopError {
    InvalidInput {
        field: &'static str,
        reason: &'static str,
    },
    TooFewSatellites,
    Singular,
}

Why a geometry has no finite DOP.

Variants

InvalidInput

A boundary input was malformed before DOP could be evaluated.

Fields

field: &'static str

Name of the malformed field.

reason: &'static str

Stable validation reason.

TooFewSatellites

Fewer line-of-sight directions than estimated parameters were supplied (four for a single clock, 3 + n_clocks for several), so the normal matrix cannot be full rank.

Singular

The normal matrix H^T W H is singular or ill-conditioned: its determinant is zero, or a variance diagonal is negative or non-finite.

Trait Implementations

impl Clone for DopError

fn clone(&self) -> DopError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DopError

impl Debug for DopError

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

Formats the value using the given formatter.

impl Display for DopError

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

Formats the value using the given formatter.

impl Eq for DopError

impl Error for DopError

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 DopError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
