Enum InvalidQuery 

pub enum InvalidQuery {
    NegativeOnly,
    ParenthesesNotSupported,
}

Errors produced by parse_query.

Variants

NegativeOnly

The query contained only negative terms with no positive terms.

This is ill-defined — it would return “all documents except those matching X”, which requires a full collection scan. Match PostgreSQL tsquery behaviour and reject the query explicitly.

ParenthesesNotSupported

The query contained NOT (...) parenthesised groups, which are not supported in this flat-only parser.

Workaround: use separate negations, e.g. rust NOT python NOT ruby instead of rust NOT (python OR ruby).

Trait Implementations

impl Clone for InvalidQuery

fn clone(&self) -> InvalidQuery

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InvalidQuery

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

Formats the value using the given formatter.

impl Display for InvalidQuery

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

Formats the value using the given formatter.

impl Error for InvalidQuery

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<E: Display> From<InvalidQuery> for FtsIndexError<E>

fn from(source: InvalidQuery) -> Self

Converts to this type from the input type.

impl PartialEq for InvalidQuery

fn eq(&self, other: &InvalidQuery) -> 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.
