Struct agdb::QueryError

pub struct QueryError {
    pub description: String,
    pub cause: Option<DbError>,
}

Universal query error returned from all query operations. It represents mainly errors from executing queries but the cause of the error may be in exceptional cases a DbError. Typically however it will contain description of a problem with running a query such as “id/alias does not exist”.

Fields

description: String

cause: Option<DbError>

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Default for QueryError

fn default() -> QueryError

Returns the “default value” for a type.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

fn source(&self) -> Option<&(dyn Error + 'static)>

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 From<&str> for QueryError

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<DbError> for QueryError

fn from(value: DbError) -> Self

Converts to this type from the input type.

impl<T> From<PoisonError<T>> for QueryError

fn from(value: PoisonError<T>) -> Self

Converts to this type from the input type.

impl From<String> for QueryError

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for QueryError

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

This method tests for self and other values to be equal, and is used by ==.

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

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