DatasetError

Struct DatasetError 

Source
pub struct DatasetError(/* private fields */);
Available on crate features dataset and std only.
Expand description

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.
