A Native encoding failure.

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.

UnsupportedColumn

A column’s ClickHouse type is not supported by the Native encoder (fatal, surfaced at construction before any row is sent).

Fields

column: String

The column name.

ch_type: String

The offending (possibly nested) type description.

TypeMismatch

The row struct’s value did not match the column’s type class.

Fields

expected: &'static str

A short label for the column type the value should have matched.

RawWidth

A fixed-width blob column (UUID/IPv6/Int256/UInt256) got the wrong number of bytes.

Fields

expected: usize

The column’s fixed width.

got: usize

The bytes the value produced.

FixedTooLong

A FixedString(N) value was longer than N.

Fields

width: usize

The column width.

got: usize

The value length.

RowArity

The row serialized a different number of fields than the schema has columns (positional mismatch).

Fields

expected: usize

Columns in the schema.

got: usize

Fields the row serialized.

FirstRecord(String)

The first record’s probed struct does not match the configured columns (pre-formatted multi-line diff). Field names and order are checked whenever the schema was fetched; under validate_schema: full this also rejects class-incompatible types per position — including a wire-wrapper scale that disagrees with the column (DateTime64Millis into DateTime64(6)).

TupleArity

A tuple/geo value serialized more elements than its column has.

NotAStruct

The row did not serialize as a struct/tuple of columns.

Internal(&'static str)

An internal invariant was violated (a bug).

Custom(String)

An error raised by a Serialize implementation.

Trait Implementations

impl Debug for NativeError

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

Formats the value using the given formatter.

impl Display for NativeError

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

Formats the value using the given formatter.

impl Error for NativeError

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 Error for NativeError

fn custom<T: Display>(msg: T) -> Self

Used when a Serialize implementation encounters any error while serializing a type.
