Why an elevation request or answer was refused.

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.

Request

A request field is outside its range.

Fields

what: &'static str

The field.

value: String

Its value; for a coordinate, followed by its place’s index from 0, as 90.5 (place 1).

Net(NetError)

The fetch failed.

Json(String)

The body is not JSON.

Server

The body is Open-Meteo’s error answer. Open-Meteo sends it with HTTP status 400, which Http reports as NetError::Transport naming the status, without the body; this error comes only from a transport that hands the body on, or a self-hosted server that answers it with status 200.

Fields

reason: String

Its reason.

Missing

A field is absent, or not of the expected type.

Fields

field: String

The field.

Count

The answer holds another number of heights than places asked for.

Fields

expected: usize

The places asked for.

found: usize

The heights in the answer.

OutOfRange

A height is outside HEIGHT_RANGE_M.

Fields

index: usize

Its place’s index in the request.

height_m: f64

The height, m.

Trait Implementations

impl Debug for ElevationError

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

Formats the value using the given formatter.

impl Display for ElevationError

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

Formats the value using the given formatter.

impl Error for ElevationError

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 From<NetError> for ElevationError

fn from(source: NetError) -> Self

Converts to this type from the input type.
