To expand on my comment, you can use rustdoc, the Rust documentation generator, to view almost everything you're asking for (at compile time). rustdoc will show:

• Structs (including public members and their impl blocks)
• Enums
• Traits
• Functions
• Any documentation comments written by the crate author with /// or //!.

rustdoc also automatically links to the source of each file in the [src] link.

Here is an example of the output of rustdoc.

Standard Library

The standard library API reference is available here and is available for anything in the std namespace.

Crates

You can get documentation for any crate available on crates.io on docs.rs. This automatically generates documentation for each crate every time it is released on crates.io.

Your Project

You can generate documentation for your project with Cargo, like so:

cargo doc

This will also automatically generate documentation for your dependencies (but not the standard library).
