Why a Wyoming 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, cut to 40 characters.

Net(NetError)

The fetch failed.

Missing

A column is absent.

Fields

field: String

The column, or header when there is no header line.

Units

A column is in a unit other than the one required.

Fields

field: &'static str

The column.

found: String

The unit it came in, cut to 40 characters.

expected: &'static str

The unit required.

Row

A line can’t be read.

Fields

line: usize

The line, counting the header as line 1.

reason: String

What is wrong with it.

NoGround

There is no ground: no row, or a first row missing a value or with one out of range.

Fields

line: usize

The line of the first row, counting the header as line 1.

GroundMisfit

A chain of rows that fit, starting after the ground among the rows it could reach, beats every chain from the ground: more rows, or as many whose layers fit more closely. The ground is taken as wrong, and it can’t be left out.

Fields

line: usize

The ground’s line, counting the header as line 1.

first: usize

The first row of that chain.

Misfit

More than MAX_MISFITS rows follow the end of the chain of rows that fit: its end, or all of them, are wrong, or rows with no temperature leave a layer too thick to check.

Fields

after: usize

The chain’s end, counting the header as line 1.

line: usize

The first row with a pressure, height and temperature within the bounds after it.

Trait Implementations

impl Debug for WyomingError

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

Formats the value using the given formatter.

impl Display for WyomingError

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

Formats the value using the given formatter.

impl Error for WyomingError

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 WyomingError

fn from(source: NetError) -> Self

Converts to this type from the input type.
