Variants

RootMismatch

Hash mismatch after sync

Fields

expected: D

actual: D

Trait Implementations

impl<F: Debug + Family, D: Debug + Digest> Debug for EngineError<F, D>

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

Formats the value using the given formatter.

impl<F: Family, D> Display for EngineError<F, D>

where D: Debug + Digest, Location<F>: Display, Target<F, D>: Debug,

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

Formats the value using the given formatter.

impl<F: Family, D: Digest> Error for EngineError<F, D>

where Self: Debug + Display,

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.
