Implementations

impl DatabaseError

pub fn with_context(self, context: OperationContext) -> DatabaseError

Add context to this error.

This wraps the error with additional context about the operation that was being performed when the error occurred.

Example

use evidentsource_core::domain::{DatabaseError, OperationContext};

let err = DatabaseError::NotFound("my-db".to_string());
let with_ctx = err.with_context(OperationContext::new("transact", "my-db"));

assert!(with_ctx.to_string().contains("transact"));

pub fn inner(&self) -> &DatabaseError

Get the inner error, stripping any context wrappers.

Trait Implementations

impl Clone for DatabaseError

fn clone(&self) -> DatabaseError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DatabaseError

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

Formats the value using the given formatter.

impl Display for DatabaseError

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

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.

impl From<DatabaseError> for StateChangeError

fn from(source: DatabaseError) -> StateChangeError

impl From<IdentifierError> for DatabaseError

fn from(source: IdentifierError) -> DatabaseError

Converts to this type from the input type.

impl From<TransactionError> for DatabaseError

fn from(source: TransactionError) -> DatabaseError
