Enum QueryError 

pub enum QueryError {
    Timeout {
        partial: bool,
    },
    Cancelled {
        partial: bool,
    },
    ReadCancelled {
        partial: bool,
    },
    Store(StoreError),
    Scan(ScanError),
    Graph(GraphSearchError),
}

Typed failure from a store-admitted query.

Variants

Timeout

The deadline expired. Partial results are never returned.

Fields

partial: bool

Permanently false; included so callers can reject future partial paths.

Cancelled

The caller cancelled the token. Partial results are never returned.

Fields

partial: bool

Permanently false; included so callers can reject future partial paths.

ReadCancelled

Store close cancelled an already admitted query.

Fields

partial: bool

Permanently false; included so callers can reject future partial paths.

Store(StoreError)

Store admission or lifecycle failed.

Scan(ScanError)

Scan validation or scoring failed.

Graph(GraphSearchError)

Graph validation or traversal failed.

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

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.
