        index: usize,
        field: String,
    },
    InvalidField {
        index: usize,

        index: usize,
        relation: String,
    },
    NotYetImplemented {
        format: String,
    },
}

An error produced by a format adapter.

Fatal errors (missing required fields, structural failures) are non-recoverable: the adapter aborts and the caller must handle the error atomically. Non-fatal issues (unknown but non-required fields) are warnings reported in the import summary.

Variants

MissingField

A required field is missing from a record.

Fields

index: usize

field: String

InvalidField

A field has an unexpected type or value.

Fields

index: usize

field: String

reason: String

Parse(String)

The source file cannot be parsed (structural failure).

UnknownKind

An entity kind is unknown under strict schema mode.

Fields

index: usize

kind: String

UnknownRelation

An edge relation is not in the closed set of 15 canonical relations.

This is always an error regardless of --schema-mode.

Fields

index: usize

relation: String

NotYetImplemented

A deferred format was requested.

Fields

format: String

Trait Implementations

impl Debug for AdapterError

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

Formats the value using the given formatter.

impl Display for AdapterError

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

Formats the value using the given formatter.

impl Error for AdapterError

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>)
