Struct fdb::error::FdbError

pub struct FdbError { /* private fields */ }

Error type for this crate.

Internally it wraps FDB Error Codes. Error codes from 100 thru’ 999 is generated by the binding layer and not the C API.

Implementations

impl FdbError

pub fn new(err: i32) -> FdbError

Create new FdbError

pub fn code(self) -> i32

Returns raw FDB error code

pub fn is_retryable(&self) -> bool

Returns true if the error indicates the operations in the transactions should be retried because of transient error.

pub fn is_maybe_committed(&self) -> bool

Returns true if the error indicates the transaction may have succeeded, though not in a way the system can verify.

pub fn is_retryable_not_committed(&self) -> bool

Returns true if the error indicates the transaction has not committed, though in a way that can be retried.

Trait Implementations

impl Clone for FdbError

fn clone(&self) -> FdbError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FdbError

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

Formats the value using the given formatter.

impl Display for FdbError

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

Formats the value using the given formatter.

impl Error for FdbError

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 PartialEq<FdbError> for FdbError

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