Implementations

impl HawDBError

pub fn from_storage_error(error: impl Error + 'static) -> Self

Preserve a descriptor rejection through nested storage error wrappers.

pub fn from_storage_error_with_context( error: impl Error + 'static, context: &str, ) -> Self

from_storage_error, prefixing a generic Storage message with context and leaving a preserved typed cause (e.g. FileDescriptors) unprefixed and unchanged.

pub const fn is_retryable_transaction_conflict(&self) -> bool

Trait Implementations

impl Clone for HawDBError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HawDBError

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

Formats the value using the given formatter.

impl Display for HawDBError

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

Formats the value using the given formatter.

impl Eq for HawDBError

impl Error for HawDBError

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 From<Error> for HawDBError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl PartialEq for HawDBError

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

Equality operator ==.

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

Inequality operator !=.
