Required Methods

fn to_opt(self) -> Result<Option<Self::Inner>>

If Ok(val), return Ok(Some(val)). If Err but the error is Error::Code(NOTFOUND), return Ok(None). Otherwise, return self.

fn ignore_exists(self, inner: Self::Inner) -> Self

Suppress KEYEXIST errors.

If this is Err and the error is Error::Code(KEYEXIST), switch to Ok with the given inner value.
