Adding Pattern Types to the Type System

RustWeek 29:44 2622 views

Oli Scherer -- Representing pattern types in the type system in a coherent way has a lot of interesting parts that no other types have had so far. I’ll talk about the lowering process from AST, over HIR, to the type system and finally into layout information. I’ll finish by explaining why generic pattern types are very incomplete so far and how we are planning to support them properly.

One year of moderation

RustNL
RustWeek 39:21 278 views

One year of moderation by Oli Scherer and Antonio Piraino. We will talk about how moderation works in the Rust project and its challenges across the project (in different venues) over the past year. We will give a quick overview about the tools we use and those we wish to have. About Oli Scherer (he/they): Oli started contributing to Rust around the 1.0 release, because attempting to replicate Ada's subtypes showed that const eval just wasn't up to it yet. In 2018 they became a compiler team member and has been maintaining parts of the Rust compiler ever since. For the last 3 years they've also been a moderation team member, navigating the various conflicts within and outside the Rust community. - git: https://github.com/oli-obk - mastodon/fedi: https://hachyderm.io/@oli About Antonio Piraino (he/him): Antonio is mostly working with the Compiler team, facilitating the organizational work (meetings, pull requests tracking, issue prioritization, etc.) in co-operation with the other project members. During the last year also helped the moderation team. - git: https://github.com/apiraino This talk was given at RustWeek 2026 as part of the Rust Project track on Wednesday 20 May.
