Expand description

The specific type of an error.

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§

source§

impl ErrorKind

source

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.
