Enum Error

pub enum Error {
    Csv(String),
    InconsistentHeaders,
    InconsistentSizeOfRows(PathBuf),
    DuplicatedColumn(String),
    ColumnNotFound(String),
    ValueError {
        data: String,
        to_type: String,
    },
    ReNoMatch(String, String),
    InvalidFormat(String),
    IOError(String),
    NoSources,
}

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

data: String

to_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

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.

impl From<Error> for Error

fn from(error: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Error

Converts to this type from the input type.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Error
