Required Methods

fn as_dyn(&self) -> &dyn HirDatabase

Manual implementation of upcasting from dyn SourceDatabase to dyn HirDatabase.

This function is needed because Rust can’t perform this upcasting automatically in the general case, as Self could be unsized.

This returns an empty list if no parameter has default.

The binders of the returned defaults are only up to (not including) this parameter.

Dyn Compatibility

This trait is dyn compatible.

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