A trait for internal dataset utilities

Internal use only. No API stability guarantees.

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Initialize all indices on this dataset based on indices from a source dataset. This will call initialize_index for each non-system index in the source dataset.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
