Struct SetupError 

pub struct SetupError;

Represents errors emitted during the startup or provisioning phase of a program.

This includes configuration loading, resource initialization, dependency setup, and other bootstrap-related failures.

Trait Implementations

impl Debug for SetupError

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

Formats the value using the given formatter.

impl Display for SetupError

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

Formats the value using the given formatter.

impl Error for SetupError

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 ThinContext for SetupError

const VALUE: Self = SetupError

The singleton value for this zero-sized error type.

fn report<C: Context>(ctx: C) -> Report<Self>

Create a new error report by converting from another context type.
