Struct BackendError 

pub struct BackendError { /* private fields */ }

Structured backend failure details.

Implementations

impl BackendError

pub fn new(kind: BackendErrorKind, message: impl Into<String>) -> Self

Construct a backend failure with an explicit class.

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

Construct a truncated backend failure.

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

Construct an unimplemented backend failure.

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

Construct an unsupported backend failure.

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

Construct a backend buffer/layout failure.

pub const fn kind(&self) -> BackendErrorKind

Return the machine-readable failure class.

pub fn message(&self) -> &str

Return the human-readable backend failure message.

Trait Implementations

impl Clone for BackendError

impl Eq for BackendError

impl Error for BackendError

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.
