Structured Errors in Rust: Weighing the Tradeoffs

2025-06-01

This article explores the advantages and disadvantages of using structured errors (e.g., with `thiserror`) versus `anyhow` in Rust applications. Based on experience maintaining a large Rust web server, the author argues that custom error types, while increasing code and maintenance overhead, offer significant benefits: clearly showing all potential failure modes of a function, improving code readability and review; creating more descriptive interfaces; avoiding redundant error messages; enforcing context addition; and allowing for extra data and functionality. However, drawbacks include increased code volume, naming challenges, maintenance overhead, and potential performance concerns. The author concludes that the trade-off should be assessed case-by-case, suggesting that in large applications, the advantages of structured errors may outweigh the costs.

Escaping the Valley: A B2B SaaS Path Less Traveled (and More Founder-Friendly)

Matt, a founder who successfully sold his company Vizzly to WPP, shares his unconventional approach to building a B2B SaaS business. He argues against the typical VC-backed path of massive funding or complete bootstrapping, advocating for a 'middle path'—raising less than $1M, retaining most equity, avoiding board seats, and focusing on profitability and asset value. This approach, while unpopular with VCs due to their high-return expectations, offers founders more control and a balanced return, mitigating the risk of significant losses in liquidation events. The author encourages entrepreneurs to choose a funding strategy aligned with their values and goals, not just VC approval.

UK to Ban Tech Used in Car Thefts: Signal Jammers Criminalized

New laws in England and Wales will ban sophisticated electronic devices used by criminals to steal cars. Over 700,000 vehicles were broken into last year, often using high-tech gadgets like signal jammers, implicated in about 40% of vehicle thefts nationwide. Previously, police needed to prove a device's use in a specific crime for prosecution; the new Crime and Policing Bill shifts the burden to the possessor to prove legitimate use. Making or selling jammers could result in five years in prison or an unlimited fine. This addresses the rise in car thefts, especially those exploiting keyless entry systems.
