    },
}

Implementations

impl RepoError

pub fn backend<E>(e: E) -> Self

where E: Error + Send + Sync + 'static,

Wrap a backend/driver error.

pub fn mapping<E>(e: E) -> Self

where E: Error + Send + Sync + 'static,

Wrap a row-mapping error.

Trait Implementations

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>)
