# Proposal ## Problem statement People often want to check some conditions at compile-time, but currently Rust does not have an intuitionistic way to do it. ## Motivating examples or...
# Proposal ## Problem statement As discussed in the 2024-01-03 T-lang triage meeting, equality for function pointers is awkward (due to "equal" functions being merged together or duplicated across different...
# Proposal ## Problem statement As of today, changing the case of a `String` is done by using methods defined on `str`, which implies that a new buffer is allocated...
# Proposal ## Motivating examples or use cases ```rs fn iter_if(cond: bool, inner: impl ExactSizeIterator) -> impl ExactSizeIterator { cond.then(|| inner).into_iter().flatten() } ``` cannot compile because > error[E0277]: the trait...
# Proposal ## Problem statement Sometimes it is not possible to run a specific test on a system because of environmental reasons. These can be skipped by using `cargo test...
# Proposal ## Problem statement There is no std-way of retrieving the devices host name. ## Motivating examples or use cases The devices host name is most commonly used as...
