Core error type for drizzle operations

Variants

ExecutionError(CompactString)

Error executing a query

PrepareError(CompactString)

Error preparing a statement

NotFound

No rows returned when at least one was expected

TransactionError(CompactString)

Error with transaction

Mapping(CompactString)

Error mapping data

Statement(CompactString)

Error in statement

Query(CompactString)

Error in query

QueryFailed

Query error with rendered SQL and parameter context.

Fields

ctx: Box<QueryContext>

Captured SQL and parameter context.

source: Box<DrizzleError>

Original error.

ParameterError(CompactString)

Error converting parameters

TryFromInt(TryFromIntError)

Integer conversion error

ParseInt(ParseIntError)

Parse int error

ParseFloat(ParseFloatError)

Parse float error

ParseBool(ParseBoolError)

Parse bool error

ConversionError(CompactString)

Type conversion error

Schema(CompactString)

Schema error (e.g. cycle in table dependencies)

UnsafeMigrationRepair

A dirty migration cannot be repaired without violating its execution safety contract.

Fields

tag: CompactString

Migration tag recorded in the tracking table.

reason: CompactString

Safety requirement that prevents automatic repair.

UnsupportedMigrationExecution

The selected adapter cannot provide a migration’s required execution semantics.

Fields

adapter: CompactString

Runtime adapter that cannot provide the required semantics.

requirement: CompactString

Migration execution capability the adapter does not provide.

Other(CompactString)

Generic error

Infallible(Infallible)

Infallible conversion error (should never happen)

Trait Implementations

impl Debug for DrizzleError

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

Formats the value using the given formatter.

impl Display for DrizzleError

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

Formats the value using the given formatter.

impl Error for DrizzleError

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.
