Enum RowDecodeError 

#[non_exhaustive]
pub enum RowDecodeError {
    Schema(SchemaError),
    Cell(CellDecodeError),
    Conversion(RowConversionError),
}

Error union returned by FromRow::from_row_with_plan.

The Schema variant lets a hand-written row decoder propagate a dynamic RowRef::cell_at lookup failure with ?.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Schema(SchemaError)

A dynamic column lookup failed, e.g. from RowRef::cell_at.

Cell(CellDecodeError)

A cell failed to decode, surfaced through RowRef::get_with_plan.

Conversion(RowConversionError)

A hand-written row decoder rejected an otherwise-decoded row.

Trait Implementations

impl Debug for RowDecodeError

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

Formats the value using the given formatter.

impl Display for RowDecodeError

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

Formats the value using the given formatter.

impl Error for RowDecodeError

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
