Or, as Dr. Berger      says, doing “cool stuff that matters”. :)    h3 idfilling-niche>a classplain href#filling-niche>“Filling a Niche”/a>/h3>    p>      I developed a a href/papers/popl22src-filling-a-niche.pdf>research project/a> that      formalized the “niche” memory layout optimization, which had never before been described in the research      literature. This optimization is used by languages including Rust and Swift to reduce the memory usage of      algebraic data types. Among other things, it allows Rust to represent code>Option&T>/code> with just a pointer,      where the null code>0x0/code> value represents the code>None/code> variant.    /p>    p>      My project a hrefhttps://popl22.sigplan.org/track/POPL-2022-student-research-competition#winners>won second        place/a> in the Undergraduate Category of the ACM SIGPLAN POPL’22 Student Research Competition.

Two-word first names are unusual and can be      confusing, so I wanted to clear it up here. I go by code>@camelid/code> on GitHub and similar names on the      official Rust Zulip and Stack Overflow, but not on any other platforms. If you see a “camelid” on another      platform, it’s probably not me.    /p>    footer>      Copyright © Noah Lev Bartell-Mangel.
