Struct RowConversionError 

pub struct RowConversionError { /* private fields */ }

Row-level conversion failure raised by a hand-written FromRow::from_row_with_plan.

Use this when decoded cells are individually valid but fail a row-level domain rule. Cell-local failures should stay CellConversionError.

Callers provide only a reason and optional source. The connector adds row_index when iteration yields the failure.

Implementations

impl RowConversionError

pub fn new(reason: impl Into<Box<str>>) -> Self

Build a row-level error with just a reason, equivalent to builder(reason).build().

pub fn builder(reason: impl Into<Box<str>>) -> RowConversionErrorBuilder

pub fn reason(&self) -> &str

pub fn source(&self) -> Option<&(dyn StdError + Send + Sync + 'static)>

pub fn row_index(&self) -> Option<usize>

Zero-based index of the failing row, filled in by the connector’s decode loop.

Trait Implementations

impl Debug for RowConversionError

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

Formats the value using the given formatter.

impl Display for RowConversionError

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

Formats the value using the given formatter.

impl Error for RowConversionError

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.

impl From<RowConversionError> for RowDecodeError

fn from(error: RowConversionError) -> Self

Converts to this type from the input type.

impl From<RowConversionError> for Error

fn from(error: RowConversionError) -> Self

Converts to this type from the input type.
