New #rustlang blog post! Learn about temporary lifetimes, about something called "temporary lifetime extension", and my idea for a new language feature called "super let".
blog.m-ou.se · Rust Temporary Lifetimes and "Super Let"The lifetime of temporaries in Rust is a complicated but often ignored topic.
In simple cases, Rust keeps temporaries around for exactly long enough,
such that we don’t have to think about them.
However, there are plenty of cases were we might not get exactly what we want, right away.
In this post, we (re)discover the rules for the lifetime of temporaries,
go over a few use cases for temporary lifetime extension,
and explore a new language idea, super let, to give us more control.
@Mara hey listen we already have a heavily abused contextful keyword
"for let" 2024
