    },
}

Error type for CSV reader operations.

Variants

IoError(Error)

I/O error (file not found, permission denied, etc.).

CsvError(String)

CSV format error from the parser.

TypeCoercion

Type coercion failure (e.g. “abc” cannot be parsed as Int64).

Fields

line: usize

column: usize

column_name: String

value: String

expected_type: String

message: String

ColumnCountMismatch

Row has a different number of columns than the schema expects.

Fields

line: usize

expected: usize

actual: usize

Trait Implementations

impl Debug for CsvReaderError

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

Formats the value using the given formatter.

impl Display for CsvReaderError

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

Formats the value using the given formatter.

impl Error for CsvReaderError

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.
