Required Methods§

Source

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

Lift “not found” errors to None.

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

Source

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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
