Implementations

impl PgError

pub fn config(message: impl Into<String>) -> Self

Create a configuration error.

pub fn connection(message: impl Into<String>) -> Self

Create a connection error.

pub fn query(message: impl Into<String>) -> Self

Create a query error.

pub fn deserialization(message: impl Into<String>) -> Self

Create a deserialization error.

pub fn type_conversion(message: impl Into<String>) -> Self

Create a type conversion error.

pub fn is_connection_error(&self) -> bool

Check if this is a connection error.

pub fn is_timeout(&self) -> bool

Check if this is a timeout error.

Trait Implementations

impl Debug for PgError

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

Formats the value using the given formatter.

impl Display for PgError

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

Formats the value using the given formatter.

impl Error for PgError

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 PgError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<PgError> for QueryError

fn from(err: PgError) -> Self

Converts to this type from the input type.

impl From<PoolError<Error>> for PgError

fn from(source: PoolError) -> Self

Converts to this type from the input type.
