Available on crate feature dynamic only.

Errors specific to dynamic schema-driven inserts.

#[non_exhaustive]: a caller matching on this must carry a _ arm. The variants stay constructible so a consumer can build one in its own tests.

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.

UnsupportedType

Column type string could not be parsed.

Fields

column: String

Column the type was declared on.

type_str: String

The type string as system.columns reported it.

EncodingError

Value could not be encoded for the target column type.

Fields

column: String

Column the value belonged to; empty for a whole-row failure.

message: String

What the encoder could not do.

SchemaMismatch

Schema mismatch detected – server rejected the insert. Retriable once the cached schema is invalidated.

Fields

table: String

Fully qualified database.table.

message: String

The server’s rejection text.

SchemaFetch

Schema fetch from system.columns failed. Retriable: a cold cache after a restart hits this on a transport blip.

Fields

table: String

Fully qualified database.table.

source: Error

The query failure, kept typed so a caller can classify it.

EmptySchema

Table has no columns (or does not exist). Retriable against a cluster that is still replicating the DDL.

Fields

table: String

Fully qualified database.table.

Trait Implementations

impl Debug for DynamicError

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

Formats the value using the given formatter.

impl Display for DynamicError

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

Formats the value using the given formatter.

impl Error for DynamicError

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<DynamicError> for Error

fn from(source: DynamicError) -> Self

Converts to this type from the input type.
