Description

1 +$0 1

should result in

std::ops::Add::add(1, 1)

(or shorter path if Add is in scope.

Note that some operators are a bit more complicated, primarily 1 == 1 is semantically equivalent to std::cmp::PartialEq::::eq(&1, &1), same for PartialOrd

Research direction

No file, test, or entry point is named in the issue. Start by tracing existing assists that transform Rust expressions and the syntax handling for binary operators, then identify the operator-to-trait method mappings and special cases such as equality and ordering. Done means the assist converts the stated operators to equivalent fully qualified method calls without changing semantics, with tests covering the examples and special cases.
