Implementations

impl OrmError

pub fn decode(column: impl Into<String>, message: impl Into<String>) -> Self

Create a decode error for a specific column

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

Create a not found error

pub fn is_unique_violation(&self) -> bool

Check if this is a unique violation error

pub fn is_not_found(&self) -> bool

Check if this is a not found error

pub fn from_db_error(err: Error) -> Self

Parse a tokio_postgres error into a more specific OrmError

Trait Implementations

impl Debug for OrmError

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

Formats the value using the given formatter.

impl Display for OrmError

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

Formats the value using the given formatter.

impl Error for OrmError

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 OrmError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<PoolError<Error>> for OrmError

Available on crate feature pool only.

fn from(err: PoolError) -> Self

Converts to this type from the input type.
