Implementations

impl DatabaseError

pub fn is_not_found(&self) -> bool

Returns true if the database error is NotFound.

Trait Implementations

impl Debug for DatabaseError

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

Formats the value using the given formatter.

impl Display for DatabaseError

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

Formats the value using the given formatter.

impl Error for DatabaseError

where Self: Debug + Display,

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

Returns the lower-level source of this error, if any.

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 ErrorCompat for DatabaseError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<BuildError> for DatabaseError

fn from(error: BuildError) -> Self

Converts to this type from the input type.

impl From<Error> for DatabaseError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for DatabaseError

fn from(error: ParseError) -> Self

Converts to this type from the input type.

impl<T> OptionalExt<T, DatabaseError> for Result<T, DatabaseError>
