Polars(PolarsError)

Polars errors (DataFrame operations)

Json(Error)

JSON parsing errors

Format(FormatError)

Format detection or parsing errors

Filter(FilterError)

Filter compilation or execution errors

Type(TypeError)

Type conversion errors

Operation(Cow<'static, str>)

General operation errors

Config(String)

Configuration errors

Multiple(Vec<Error>)

Multiple errors collected during processing

Implementations

impl Error

pub fn operation(msg: impl Into<Cow<'static, str>>) -> Self

Create an operation error with a custom message

pub fn config(msg: impl Into<String>) -> Self

Create a configuration error with a custom message

pub fn from_operation_error(msg: impl Into<Cow<'static, str>>) -> Self

Create an operation error from shared utility

pub fn from_config_error(msg: impl Into<String>) -> Self

Create a configuration error from shared utility

pub fn combine(errors: Vec<Error>) -> Self

Combine multiple errors into a single error

Trait Implementations

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 StdError + '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.
