An error that can occur when processing CSV data.

This error can happen when writing or reading CSV data.

There are some important scenarios where an error is impossible to occur. For example, if a CSV reader is used on an in-memory buffer with the flexible option enabled and one is reading records as raw byte strings, then no error can occur.

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 of Utf8

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 of UnequalLengths

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 of Deserialize

pos: Option<Position>	The position of this error, if available.
err: DeserializeError	The deserialization error.

Trait Implementations

impl Debug for Error

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl From<Error> for Error

fn from(err: Error) -> Error

Performs the conversion.

impl StdError for Error

fn description(&self) -> &str

A short description of the error.

fn cause(&self) -> Option<&StdError>

The lower-level cause of this error, if any.

impl Display for Error

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

Formats the value using the given formatter.

impl SerdeError for Error

fn custom<T: Display>(msg: T) -> Error
