Error type for storage-directed conversion failures.

Variants

Unsupported

Conversion between these types is not supported.

Fields

from: &'static str

Source Rust type name.

to: &'static str

Target storage type name.

OutOfRange

Value is out of range for the target type.

Fields

from: &'static str

Source Rust type name.

to: &'static str

Target storage type name.

index: Option<usize>

Failing element index for vector conversions.

NonFinite

Value is non-finite (NaN or Inf) but target requires finite.

Fields

to: &'static str

Target storage type name.

index: Option<usize>

Failing element index for vector conversions.

PrecisionLoss

Conversion would lose precision.

Fields

to: &'static str

Target storage type name.

index: Option<usize>

Failing element index for vector conversions.

NotIntegral

Float value is not integral but target is integer type.

Fields

to: &'static str

Target storage type name.

index: Option<usize>

Failing element index for vector conversions.

MissingValue

Missing value (NA) cannot be represented in target type.

Fields

to: &'static str

Target storage type name.

index: Option<usize>

Failing element index for vector conversions.

InvalidUtf8

Invalid UTF-8 in string conversion.

Fields

index: Option<usize>

Failing element index for vector conversions.

Implementations

impl StorageCoerceError

pub fn at_index(self, idx: usize) -> Self

Add index information to the error.

Trait Implementations

impl Clone for StorageCoerceError

fn clone(&self) -> StorageCoerceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageCoerceError

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

Formats the value using the given formatter.

impl Display for StorageCoerceError

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

Formats the value using the given formatter.

impl Error for StorageCoerceError

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 StorageCoerceError

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