Represents errors that can occur during analysis operations, including database interactions.

Variants

DriverError(Error)

An error originating from the underlying database driver (neo4rs).

ConnectionFailed(String)

Failed to establish an initial connection to the database.

ProjectionDropFailed

An error occurred while attempting to drop an existing GDS graph projection.

Fields

projection_name: String

source_error: String

ProjectionCreationFailed

An error occurred during the creation of a GDS graph projection.

Fields

projection_name: String

source_error: String

QueryFailed(String)

A generic error for database query execution failures not covered by other specific variants.

ProjectionNotFound(String)

Indicates that a requested GDS graph projection was not found.

ProjectionAlreadyExists(String)

Indicates that a GDS graph projection already exists when it was not expected.

AlgorithmError(String)

An error occurred during the execution of a graph algorithm.

ConfigurationError(String)

For configuration-related errors during analysis setup.

IoError(Error)

For I/O errors that might occur (e.g., reading a script file for a query).

Generic(String)

For any other general error encountered during analysis.

Trait Implementations

impl Debug for AnalysisError

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

Formats the value using the given formatter.

impl Display for AnalysisError

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

Formats the value using the given formatter.

impl Error for AnalysisError

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.
