Errors from opening or reading an InputSource.

Variants

Io(Error)

Local I/O error.

Parquet(ParquetError)

Parquet error (footer parse, reader construction).

UnsupportedScheme

The input looks like a URL but uses a scheme we do not support.

Fields

scheme: String

The unrecognized scheme.

url: String

The full input string.

RemoteDisabled(String)

A remote URL was supplied but the crate was built without remote.

Arrow(ArrowError)

Arrow error surfaced while decoding record batches from a stream.

IncompatiblePartition

A partition of a multi-file input does not match the first partition (schema shape, geometry extension metadata, or CRS).

Fields

first: String

Display name of the reference (first) partition.

offender: String

Display name of the partition that failed validation.

detail: String

What differs.

NoParquetInputs

A directory or glob input matched no .parquet files.

Fields

input: String

The original input string (directory path or glob pattern).

RemotePrefixUnsupported

An http(s):// URL naming a prefix (“directory”). Generic HTTP has no listing API, so the objects must be named explicitly; s3:// and gs:// prefixes are listed natively.

Fields

url: String

The rejected URL.

ManifestRead

The --files-from manifest itself could not be read.

Fields

path: String

The manifest path as supplied.

source: Error

The underlying I/O error.

MissingListedInput

An explicitly listed input (a --files-from manifest line or a Python input-list entry) does not exist as a local file. Listed entries are single files/objects only — no directory, glob, or prefix expansion.

Fields

context: String

Where the entry came from (manifest line / list position).

input: String

The offending entry.

GlobPattern

A glob input string is not a valid glob pattern.

Fields

pattern: String

The pattern as supplied.

message: String

The glob crate’s error message.

Trait Implementations

impl Debug for InputError

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

Formats the value using the given formatter.

impl Display for InputError

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

Formats the value using the given formatter.

impl Error for InputError

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.

impl From<ArrowError> for InputError

fn from(source: ArrowError) -> Self

Converts to this type from the input type.

impl From<Error> for InputError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<InputError> for ConvertError

fn from(source: InputError) -> Self

Converts to this type from the input type.

impl From<ParquetError> for InputError

fn from(source: ParquetError) -> Self

Converts to this type from the input type.
