Enum CypherError 

pub enum CypherError {
    ParseError(String),
    Unsupported(String),
    InvalidQuery(String),
    TypeMismatch(String),
    DivisionByZero,
    RuntimeError(String),
}

Errors that can occur when parsing or evaluating a Cypher query.

Variants

ParseError(String)

The query string could not be parsed.

Unsupported(String)

A feature required by the query is not yet implemented.

InvalidQuery(String)

The query is structurally invalid (e.g. an unresolved variable).

TypeMismatch(String)

A runtime type mismatch occurred during expression evaluation.

DivisionByZero

Division by zero during expression evaluation.

RuntimeError(String)

An invalid operation was requested at runtime.

Trait Implementations

impl Debug for CypherError

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

Formats the value using the given formatter.

impl Display for CypherError

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

Formats the value using the given formatter.

impl Error for CypherError

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 PartialEq for CypherError

fn eq(&self, other: &CypherError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
