Enum CoreError 

pub enum CoreError {
    Unimplemented(&'static str),
    Diagnostic(Box<Diagnostic>),
}

Convenience top-level error type for crates that want a single Result alias without inventing their own.

Examples

use mos_core::CoreError;

let err = CoreError::Unimplemented("cache");

assert_eq!(err.to_string(), "not yet implemented: cache");

Variants

Unimplemented(&'static str)

Diagnostic(Box<Diagnostic>)

Trait Implementations

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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.
