Enum ConversionError 

pub enum ConversionError {
    UnsupportedCountry,
    NotConvertible {
        reason: &'static str,
    },
    Validation(ValidationError),
}

Error returned when one identifier cannot be converted into another.

A conversion can fail because the source identifier’s country has no defined target (e.g. extracting a CUSIP from a non-US/CA ISIN), because the converted value is not itself a valid identifier, or because a ValidationError surfaced while building the target.

Examples

use regit_identifiers::errors::{ConversionError, ValidationError};

// A validation error converts into a ConversionError with `?`.
let err: ConversionError = ValidationError::Empty.into();
assert!(matches!(err, ConversionError::Validation(ValidationError::Empty)));

Variants

UnsupportedCountry

The source identifier’s country has no defined target for this conversion (e.g. extracting a CUSIP from a non-US/CA ISIN).

NotConvertible

The conversion produced a value that is not itself valid; reason names the problem.

Fields

reason: &'static str

A short, human-readable description of why the value is invalid.

Validation(ValidationError)

A validation error surfaced while building the converted identifier.

Trait Implementations

impl Clone for ConversionError

fn clone(&self) -> ConversionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl Display for ConversionError

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

Formats the value using the given formatter.

impl Error for ConversionError

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<ValidationError> for ConversionError

fn from(e: ValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for ConversionError

fn eq(&self, other: &ConversionError) -> 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.
