Standards to follow when writing Rust documentation.
Guidelines
Key concepts should be explained only once. All other documentation should use an intra-documentation link to the first explanation.
Always use an intra-documentation link when mentioning a Rust symbol (type, function, constant, etc.).
Avoid referring to specific lines or line ranges, as they may change over time.
Use line comments if the documentation needs to be attached to a specific code section inside
a function/method body.
Focus on why, not how.
In particular, avoid explaining trivial implementation details in line comments.
Refer to constants using intra-documentation links. Don't hard-code their values in the documentation of other items.
Intra-documentation links to private items are preferable to duplication. Add
