Struct RowParseError 

pub struct RowParseError {
    pub row: u64,
    pub column: Option<String>,
    pub raw_sample: String,
    pub message: String,
}

Structured per-record parse failure. Carries the user-visible row number, an optional column attribution (CSV cell parses), a truncated sample of the raw bytes that failed, and the underlying message. Boxed into std::io::Error via row_parse_io_error so it travels through the standard feed / finish return type; recoverable via downcast_row_parse_error.

Fields

row: u64

1-indexed record number. For CSV the header is record 0 and the first data row is record 1; for JSONL/JSON-array the first object is record 1. Records that fail mid-parse still take a slot in this sequence.

column: Option<String>

Column name when the failure is attributable to a single cell (CSV typed cell). None for whole-record failures and JSON-based formats.

raw_sample: String

Truncated raw bytes (or characters) from the offending record. Capped to keep error payloads bounded.

message: String

Human-readable description of what went wrong.

Implementations

impl RowParseError

pub fn make_sample(raw: &str) -> String

Build a raw_sample from the offending text, replacing any non-printable control characters with · (middle dot) and truncating at RAW_SAMPLE_MAX_CHARS with a trailing ….

pub fn make_sample_from_bytes(raw: &[u8]) -> String

Build a sample from a byte slice, treating non-UTF-8 bytes with the lossy replacement char.

Trait Implementations

impl Clone for RowParseError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RowParseError

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

Formats the value using the given formatter.

impl Display for RowParseError

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

Formats the value using the given formatter.

impl Error for RowParseError

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.
