描述

if a struct has a new or a from method that does the same as a struct constructor, then that method should be used instead of the struct constructor.

Obviously the usage of a struct constructor inside the new or from method should not be linted.

研究方向
Start by reading the clippy documentation for contributing new lints. Look at the `clippy lints` directory for examples of lints that check function calls, such as `new ret no self` (file: clippy lints/src/new ret no self.rs). Understand how to implement a lint pass that checks struct expressions and compares them to available new/from methods. Review the issue comments for any additional design considerations.
