Struct DatasetError 

pub struct DatasetError(/* private fields */);

Default error type used by Dataset implementations that don’t define their own.

Wraps specific dataset error types (e.g. SqliteDatasetError) at call sites that don’t need the concrete error type. Use result.map_err(DatasetError::new)? to convert and propagate an error; ? alone does not perform this wrapping.

Implementations

impl DatasetError

pub fn new<E>(err: E) -> Self

where E: Error + Send + Sync + 'static,

Wraps an arbitrary error as a DatasetError.

Trait Implementations

impl Debug for DatasetError

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

Formats the value using the given formatter.

impl Display for DatasetError

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

Formats the value using the given formatter.

impl Error for DatasetError

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.
