    Io(Error),
    Utf8 {
        pos: Option<Position>,
        err: Utf8Error,
    },

}

The specific type of an error.

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.

Io(Error)

An I/O error that occurred while reading CSV data.

Utf8

A UTF-8 decoding error that occured while reading CSV data into Rust Strings.

Fields

pos: Option<Position>

The position of the record in which this error occurred, if available.

err: Utf8Error

The corresponding UTF-8 error.

UnequalLengths

This error occurs when two records with an unequal number of fields are found. This error only occurs when the flexible option in a CSV reader/writer is disabled.

Fields

pos: Option<Position>

The position of the first record with an unequal number of fields to the previous record, if available.

expected_len: u64

The expected number of fields in a record. This is the number of fields in the record read prior to the record indicated by pos.

len: u64

The number of fields in the bad record.

Seek

This error occurs when either the byte_headers or headers methods are called on a CSV reader that was asked to seek before it parsed the first record.

Serialize(String)

An error of this kind occurs only when using the Serde serializer.

Deserialize

An error of this kind occurs only when performing automatic deserialization with serde.

Fields

pos: Option<Position>

The position of this error, if available.

err: DeserializeError

The deserialization error.

Implementations

impl ErrorKind

pub fn position(&self) -> Option<&Position>

Return the position for this error, if one exists.

This is a convenience function that permits callers to easily access the position on an error without doing case analysis on ErrorKind.

Trait Implementations

impl Debug for ErrorKind

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

Formats the value using the given formatter.
