Implementations

impl DatabaseError

pub fn interact(msg: &(impl ToString + ?Sized), e: &InteractError) -> Self

Converts from InteractError

Note: Required since InteractError has at least one enum variant that is not Send + Sync and hence prevents the Sync auto implementation. This does an internal conversion to string while maintaining convenience.

Using MSG as const so it can be called as .map_err(DatabaseError::interact::<"Your message">)

pub fn conversiont_from_sql<RT, E, MaybeE>(err: MaybeE) -> DatabaseError

where MaybeE: Into<Option<E>>, E: Error + Send + Sync + 'static,

Failed to convert an SQL entry to a rust representation

pub fn deserialization( context: &'static str, source: impl Error + Send + Sync + 'static, ) -> Self

Creates a deserialization error with a static context string and the original error.

This is a convenience wrapper around ConversionSqlToRust.

Trait Implementations

impl Debug for DatabaseError

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

Formats the value using the given formatter.

impl Display for DatabaseError

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

Formats the value using the given formatter.

impl Error for DatabaseError

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.
