Struct WriterError 

pub struct WriterError { /* private fields */ }

item writer failed

The adapter translates its own typed error into a stable FailureCategory at this boundary. The payload, display text, and source chain are dropped, so classification never inspects them.

Implementations

impl WriterError

pub const fn new() -> Self

Constructs a value-redacted FailureCategory::UserComponent failure.

pub const fn with_category(category: FailureCategory) -> Self

Constructs a failure that declares its own stable category.

A category that is not policy-eligible fails closed: the fault is never retried or skipped.

pub fn from_error(error: impl Error + Send + Sync + 'static) -> Self

Classifies an arbitrary user error without retaining its payload or display text.

pub const fn category(self) -> FailureCategory

Returns the stable category supplied by the adapter.

impl WriterError

pub const fn with_rolled_back_output(self, index: usize) -> Self

Records that the batch is known to have rolled back and identifies the single failed output by its zero-based index in the supplied batch.

A write skip requires this evidence. An unlocated, partially visible, or ambiguous write cannot be skipped.

pub const fn rolled_back_output(self) -> Option<usize>

Returns the located failed output index, when the writer supplied one.

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
