}

A didactic error explaining why a file could not be materialized.

Every variant renders to a human-readable, non-panicking message: a missing, unreadable, unsupported, or malformed file never aborts the process abnormally.

Variants

NotAFile

The path does not point at a readable regular file.

Fields

path: String

UnsupportedExtension

The extension is not one of the ephemeral data formats.

Fields

path: String

ext: String

EmptyStem

The file stem sanitized to an empty identifier.

Fields

path: String

Import

The CSV import path rejected the file (I/O or parse failure).

Fields

path: String

source: String

Json

The JSON or NDJSON document parser rejected the file.

Fields

path: String

source: String

JsonShape

A JSON file parsed successfully but was not an array of objects.

Fields

path: String

source: String

Trait Implementations

impl Debug for EphemeralError

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

Formats the value using the given formatter.

impl Display for EphemeralError

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

Formats the value using the given formatter.

impl Error for EphemeralError

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>)
