Unnecessary path prefixes

[alice-i-cecile]

What it does

Strips out unnecessary path qualifiers on types/functions/structs when the module they are being imported from is already in scope.

See bevyengine/bevy#10749 for an example of this in practice, powered by RustRover's refactoring tools.

Advantage

• clarifies that this is the standard, already imported form
• reduces noise and saves characters

Drawbacks

Maybe makes imports less clear in cases where you really want to be explicit?

This is a weaker version of absolute_paths, focused on redundancy rather than enforcing a universal style. In some cases, you might want the latter.

Example

use bevy::prelude::*;

let world = bevy::ecs::World::new();

Could be written as:

use bevy::prelude::*;

let world = World::new();

There exists a rustc lint which is allowed-by-default: unused_qualifications
