An enumeration of LiquidML errors.

Variants

RowIndexOutOfBounds

Attempted to access a row in a DataFrame that is out of bounds

ColIndexOutOfBounds

Attempted to access a column in a DataFrame that is out of bounds

NameAlreadyExists

Attempted to add or re-name a Column in a DataFrame to a name that is already in use in that DataFrame

TypeMismatch

Attempted to perform an operation that conflicts with a DataFrames schema, e.g. attempting to use set_int for a column that is of type String

NetworkError(Error)

A generic error when there is an underlying error with a TCP connection

SerdeError(Box<ErrorKind>)

An error when serializing or deserializing

UnknownId

An error when trying to send messages to nodes that are not currently connected to this node

ReconnectionError

An error when multiple connections are made to the same id

NotPresent

An error when trying to get a value from a KVStore that does not exist at that KVStore

StreamClosed

An error when a connection is closed unexpectedly

UnexpectedMessage

An error when messages are received unexpectedly, e.g. when a Client is starting up and messages other than ControlMsgs are received

Trait Implementations

impl Debug for LiquidError

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

Formats the value using the given formatter.

impl Display for LiquidError

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

Formats the value using the given formatter.

impl Error for LiquidError

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<Box<ErrorKind>> for LiquidError

fn from(source: Box<ErrorKind>) -> Self

Converts to this type from the input type.

impl From<Error> for LiquidError

fn from(source: Error) -> Self

Converts to this type from the input type.
