Enum Error 

#[non_exhaustive]
pub enum Error {
    UnknownCrs(String),
    UnsupportedProjection(String),
    UnknownOperation(String),
    OperationSelection(String),
    InvalidDefinition(String),
    OutOfRange(String),
    NonConvergence {
        context: &'static str,
        iterations: usize,
    },
    Grid(GridError),
}

Errors produced by CRS resolution, transform construction, and coordinate conversion.

The enum is #[non_exhaustive]: match the variants you handle and keep a wildcard arm. Message payloads carry human-readable context; structured variants are added as concrete matching needs appear.

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.

UnknownCrs(String)

UnsupportedProjection(String)

UnknownOperation(String)

OperationSelection(String)

InvalidDefinition(String)

OutOfRange(String)

NonConvergence

A fixed-point iteration exhausted its budget without meeting its tolerance: the input is outside the domain where the inverse series contracts.

Fields

context: &'static str

iterations: usize

Grid(GridError)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<GridError> for Error

fn from(source: GridError) -> Self

Converts to this type from the input type.
