Enum StructureBatchError 

pub enum StructureBatchError {
    Diagnostic(Diagnostic),
    DemandTooSmall {
        required: usize,
        available: usize,
    },
    RecordExceedsBudget {
        required: usize,
        available: usize,
    },
    Identity(ProviderError),
    Memory(MemoryBudgetError),
    DictionaryFull,
}

Failure shared by bounded structural batch readers and collectors.

Variants

Diagnostic(Diagnostic)

A source, syntax or semantic diagnostic.

DemandTooSmall

A single record cannot fit the caller’s row or byte demand.

Fields

required: usize

Minimum retained bytes required.

available: usize

Retained bytes offered by the demand.

RecordExceedsBudget

A single indivisible record cannot fit the execution budget.

Fields

required: usize

Minimum bytes required for the indivisible record.

available: usize

Bytes available to the source stage.

Identity(ProviderError)

Stable dataset, chunk or logical-row arithmetic overflowed.

Memory(MemoryBudgetError)

Execution memory was exhausted after source advancement was prevented.

DictionaryFull

A batch-local identifier dictionary was exhausted.

Trait Implementations

impl Debug for StructureBatchError

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

Formats the value using the given formatter.

impl Display for StructureBatchError

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

Formats the value using the given formatter.

impl Error for StructureBatchError

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<&StructureBatchError> for Diagnostic

fn from(error: &StructureBatchError) -> Self

A wrapped diagnostic is returned as it is, so its code, remedy and span survive; the rest name the kind of limit that stopped the read.

impl From<Diagnostic> for StructureBatchError

fn from(error: Diagnostic) -> Self

Converts to this type from the input type.

impl From<DictionaryFull> for StructureBatchError

fn from(_: DictionaryFull) -> Self

Converts to this type from the input type.

impl From<MemoryBudgetError> for StructureBatchError

fn from(error: MemoryBudgetError) -> Self

Converts to this type from the input type.

impl From<ProviderError> for StructureBatchError

fn from(error: ProviderError) -> Self

Converts to this type from the input type.

impl From<StructureBatchError> for Diagnostic

fn from(error: StructureBatchError) -> Self

Converts to this type from the input type.
