type Validation: Error

The validation error returned by validate_merge.

Required Methods§

source

fn validate_merge(&self, other: &Self) -> Result<(), Self::Validation>

Some CRDT’s have stricter requirements on how they must be used. To avoid violating these requirements, CRDT’s provide an interface to optionally validate merge compatibility before attempting to merge.

An Ok(()) response signals that the merge is safe to proceed. Otherwise a structured error is returned to help you determine what is wrong with the merge.
