Error while compiling CSV into a MaxMind DB.

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.

Io(Error)

Failed to read from the input.

Parse

A row could not be parsed; carries the 1-based record number and reason.

Fields

record: usize

1-based record number of the offending row (records, not physical lines — a quoted field may span several lines).

reason: Box<str>

Why the row could not be parsed.

Write(MmdbWriteError)

The in-memory database could not be written (e.g. overlapping ranges).

Build(GeoIpError)

The compiled bytes could not be read back as a database.

Trait Implementations

impl Debug for CsvError

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

Formats the value using the given formatter.

impl Display for CsvError

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

Formats the value using the given formatter.

impl Error for CsvError

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.
