- Many more functions are marked
#[must_use], producing a warning
``
``

`+
when ignoring their return value. This helps catch mistakes such as expecting
`
``
32
`+
a function to mutate a value in place rather than return a new value.

Internal changes

improvements to the internals and overall performance of rustc
