Struct agdb::DbError

pub struct DbError {
    pub description: String,
    pub cause: Option<Box<DbError>>,
    pub source_location: Location<'static>,
}

Universal agdb database error. It represents any error caused by the database processing such as loading a database, writing data etc.

Fields

description: String

Error description

cause: Option<Box<DbError>>

Optional error that caused this error

source_location: Location<'static>

Location where the error originated in the sources

Implementations

impl DbError

pub fn caused_by(self, error: Self) -> Self

Sets the cause of this error to error.

Trait Implementations

impl Debug for DbError

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

Formats the value using the given formatter.

impl Display for DbError

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

Formats the value using the given formatter.

impl Error for DbError

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 From<&str> for DbError

fn from(description: &str) -> Self

Converts to this type from the input type.

impl From<DbError> for QueryError

fn from(value: DbError) -> Self

Converts to this type from the input type.

impl From<Error> for DbError

fn from(error: IOError) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for DbError

fn from(error: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<String> for DbError

fn from(description: String) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for DbError

fn from(error: TryFromIntError) -> Self

Converts to this type from the input type.

impl From<TryFromSliceError> for DbError

fn from(error: TryFromSliceError) -> Self

Converts to this type from the input type.

impl PartialEq for DbError

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