Enum IngestionError 

pub enum IngestionError {
    Io(Error),
    Csv(Error),
    Parquet(ParquetError),
    Engine {
        message: String,
        source: Box<dyn StdError + Send + Sync + 'static>,
    },
    SchemaMismatch {
        message: String,
    },
    ParseError {
        row: usize,
        column: String,
        raw: String,
        message: String,
    },
}

Error type returned by ingestion functions.

This is a single error enum shared across CSV/JSON/Parquet/Excel ingestion.

Variants

Io(Error)

Underlying I/O error (e.g. file not found, permission denied).

Csv(Error)

CSV ingestion error.

Parquet(ParquetError)

Parquet ingestion error.

Engine

Underlying engine error (e.g. Polars, optional SQL engine), preserved with a source chain.

This is used when the engine produces a structured error that callers may want to inspect or log in detail. The top-level message is a stable, human-readable summary, while the original engine error is preserved via std::error::Error::source.

Fields

message: String

source: Box<dyn StdError + Send + Sync + 'static>

SchemaMismatch

The input does not conform to the provided schema (missing required fields/columns, etc.).

Fields

message: String

ParseError

A value could not be parsed into the required crate::types::DataType.

Fields

row: usize

column: String

raw: String

message: String

Trait Implementations

impl Debug for IngestionError

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

Formats the value using the given formatter.

impl Display for IngestionError

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

Formats the value using the given formatter.

impl Error for IngestionError

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<Error> for IngestionError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for IngestionError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParquetError> for IngestionError

fn from(source: ParquetError) -> Self
