Implementations

impl Error

pub fn database(msg: impl AsRef<str>) -> Self

Build a Error::Database with URL userinfo redacted from the message.

pub fn database_with_source( msg: impl AsRef<str>, source: impl Error + Send + Sync + 'static, ) -> Self

Build a Error::Database with a typed source cause and redacted message.

pub fn serialization(e: Error) -> Self

Build a Error::Serialization that preserves the serde_json cause.

pub fn serialization_msg(msg: impl Into<String>) -> Self

Build a Error::Serialization from a message when no serde cause is available.

pub fn is_retryable_transaction_contention(&self) -> bool

True when the database engine reported MVCC / transaction contention that may succeed on retry.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<&str> for Error

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
