Enum QueryError 

#[non_exhaustive]
pub enum QueryError {
    DoesNotExist,
    MultipleObjectsReturned(u64),
    InvalidPlan(String),
    TransactionClosed,
    TransactionAborted,
    TransactionBusy,
    Model(String),
    Decode {
        column: String,
        reason: String,
    },
}

The query plan is invalid independent of any backend.

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.

DoesNotExist

get() matched no rows.

MultipleObjectsReturned(u64)

get() matched more than one row.

InvalidPlan(String)

Structural problem in the plan.

TransactionClosed

A statement ran on a transaction that was already committed or rolled back.

TransactionAborted

Cancelled or failed scope cleanup made this transaction unusable.

TransactionBusy

Another statement or child scope owns this transaction connection.

Model(String)

A model or relation was used in a way its metadata does not allow.

Decode

A decoded value had an unexpected type.

Fields

column: String

Column name.

reason: String

Reason.

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Eq for QueryError

impl Error for QueryError

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<QueryError> for OrmError

fn from(source: QueryError) -> Self

Converts to this type from the input type.

impl PartialEq for QueryError

fn eq(&self, other: &QueryError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
