Implementations

impl EFError

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

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

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

pub fn model_validation(msg: impl Into<String>) -> Self

pub fn migration(msg: impl Into<String>) -> Self

pub fn provider(msg: impl Into<String>) -> Self

pub fn configuration(msg: impl Into<String>) -> Self

pub fn change_tracking(msg: impl Into<String>) -> Self

pub fn transaction(msg: impl Into<String>) -> Self

pub fn concurrency_conflict(msg: impl Into<String>) -> Self

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

pub fn other(msg: impl Into<String>) -> Self

pub fn with_source(self, source: BoxError) -> Self

Attaches a source error to this EFError, preserving the error chain.

pub fn message(&self) -> &str

Extracts the human-readable message without the source chain.

pub fn code(&self) -> EFErrorCode

Returns a stable EFErrorCode for programmatic dispatch.

Sub-categories within a variant are detected via case-insensitive message patterns (e.g. "timeout" → ConnectionTimeout). Messages are stable internal strings produced by rust-ef’s own call sites; user-supplied messages from EFError::other fall back to Unknown.

Trait Implementations

impl Debug for EFError

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

Formats the value using the given formatter.

impl Display for EFError

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

Formats the value using the given formatter.

impl Error for EFError

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<DbValueConvertError> for EFError

fn from(e: DbValueConvertError) -> Self

Converts to this type from the input type.
