Enum RowBinaryError 

#[non_exhaustive]
pub enum RowBinaryError {
    Unsupported(&'static str),
    SequenceMustHaveLength,
    FlattenUnsupported,
    NestedOption,
    FieldCountMismatch {
        expected: usize,
        got: usize,
    },
    VariantOutOfRange(u32),
    Custom(String),
}

A row failed to serialize. Record-level: subject to the sink stage’s error policy, never fatal to the pipeline by itself.

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.

Unsupported(&'static str)

The Rust type has no RowBinary representation.

SequenceMustHaveLength

Sequences must know their length up front (LEB128 prefix).

FlattenUnsupported

#[serde(flatten)] (serde serializes the outer struct as a length-less map, which RowBinary cannot position into columns).

NestedOption

A nested Option (Option<Option<T>>): ClickHouse has no Nullable(Nullable(T)), so the double null-prefix is unparseable.

FieldCountMismatch

A Serialize impl declared one struct field count to serialize_struct but serialized a different number of fields. RowBinary is positional, so a variable-width row misaligns every following column. (Note: #[serde(skip)]/#[serde(skip_serializing_if)] evade this check — serde reports the post-skip count — which is why those attributes are documented as unsupported.)

Fields

expected: usize

Fields the Serialize impl declared.

got: usize

Fields it actually serialized.

VariantOutOfRange(u32)

Variant discriminants are single bytes.

Custom(String)

An error raised by a Serialize implementation.

Trait Implementations

impl Debug for RowBinaryError

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

Formats the value using the given formatter.

impl Display for RowBinaryError

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

Formats the value using the given formatter.

impl Error for RowBinaryError

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 RowBinaryError

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

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