What commenters say

• The article's use of tangential topics and tools, such as cargo-edit and tracing, is seen as both helpful and distracting by different readers.
• Some readers appreciate the article's in-depth explanation of Rust futures, while others find it too lengthy and meandering.
• The use of generics in Rust is seen as both powerful and cumbersome, with some readers wishing for a more concise way to express complex type constraints.
• The article's style and structure are seen as well-suited for experienced programmers looking to deepen their understanding of Rust, but potentially overwhelming for beginners.
• Readers disagree on the importance of testing and validating code examples in tutorials and documentation, with some arguing it is essential and others seeing it as unnecessary.
• The article's discussion of async programming in Rust is seen as helpful and informative, but some readers prefer other resources, such as the Tokio tutorial or the 'Writing an OS in Rust' series.
• Some readers appreciate the author's use of anecdotes and personal experience to illustrate complex concepts, while others find it unhelpful or confusing.
