}

Errors returned by Row::get

Variants

NotFound

The requested index was not found

Fields

index: RowIndex<'i>

The index which has not been found

MismatchedTypes

The type returned by the database and the type expected by rust don’t match.

This is checked before decoding is even attempted.

Fields

index: RowIndex<'i>

The index the error occurred at

rust_type: &'static str

The type_name of the expected type

UnexpectedNull

An unexpected NULL was encountered during decoding.

This is a special case of RowError::Decode which the caller could handle by wrapping the type to decode in an Option.

Fields

index: RowIndex<'i>

The index the error occurred at

Decode

An error occurred while decoding the value.

Fields

index: RowIndex<'i>

The index the error occurred at

source: Box<dyn Error + Send + Sync>

The error produced by the Decode implementation

Unknown

An unknown error occurred.

Fields

index: RowIndex<'i>

The index the error occurred at

source: Box<dyn Error + Send + Sync>

The underlying error which could not be mapped to one of this enum’s variants.

This is an sqlx::Error which should not happen according to their documentation.

Implementations

impl<'i> RowError<'i>

pub fn index(&self) -> RowIndex<'i>

The index the error occurred at

pub fn into_owned(self) -> OwnedRowError

Converts the error into its owned version

Trait Implementations

impl<'i> Debug for RowError<'i>

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

Formats the value using the given formatter.

impl<'i> Display for RowError<'i>

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

Formats the value using the given formatter.

impl<'i> Error for RowError<'i>

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<'i> From<RowError<'i>> for Error

fn from(value: RowError<'i>) -> Self

Converts to this type from the input type.

impl<'i> From<RowError<'i>> for OwnedRowError

fn from(value: RowError<'i>) -> Self

Converts to this type from the input type.
