An error found somewhere in the transformation chain.

Variants

Csv(String)

An error ocurred in the underlaying csv library, likely a permissions issue.

InconsistentHeaders

The headers of two of the input csv files do not match each other.

InconsistentSizeOfRows(PathBuf)

A stream was found that has a row with different number of fields than the rest.

DuplicatedColumn(String)

You tried to add a column to the stream but that name was alredy in use.

ColumnNotFound(String)

You tried to use a column as source for something but that column does not exist.

ValueError

An error ocurred trying to convert a value from string to a different data type.

Fields of ValueError

data: Stringto_type: String

ReNoMatch(String, String)

String didn't match regular expression. Likely in the .add() method.

InvalidFormat(String)

Template string for defining a new column had an invalid format.

IOError(String)

An IO error ocurred, and this is its representation.

NoSources

You atempted to create a row stream without adding any source files.

Trait Implementations

impl Clone for Error

pub fn clone(&self) -> Error

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

pub fn source(&self) -> Option<&(dyn Error + 'static)>

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

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

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

pub fn from(error: Error) -> Error

Performs the conversion.

impl From<Error> for Error

pub fn from(error: Error) -> Error

Performs the conversion.

impl PartialEq<Error> for Error

pub fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Error) -> bool

This method tests for !=.
