Enum ArrowToLogicalSchemaError 

#[non_exhaustive]
pub enum ArrowToLogicalSchemaError {
    Unsupported {
        column: String,
        data_type: DataType,
    },
    InvalidArrowLogicalSchema {
        source: LogicalSchemaValidationError,
    },
}

Errors converting an Arrow schema into the table logical schema model.

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

An Arrow type cannot be represented exactly by the logical schema model.

Fields

column: String

Dotted field path containing the unsupported type.

data_type: DataType

Unsupported Arrow data type.

InvalidArrowLogicalSchema

The converted fields do not form a valid logical schema.

Fields

source: LogicalSchemaValidationError

Logical schema validation failure.

Trait Implementations

impl Debug for ArrowToLogicalSchemaError

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

Formats the value using the given formatter.

impl Display for ArrowToLogicalSchemaError

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

Formats the value using the given formatter.

impl Error for ArrowToLogicalSchemaError

where Self: Debug + Display,

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 ErrorCompat for ArrowToLogicalSchemaError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
