In some setups the rust compiler emits errors like the following:
-----------------------------------------------------------------------
error: hiding a lifetime that's elided elsewhere is confusing
--> ../subprojects/proc-macro2-1.0.86/src/parse.rs:125:25
|
125 | fn block_comment(input: Cursor) -> PResult<&str> {
| ^^^^^^ -------------
| | | |
| | | the same lifetime is elided here
| | the same lifetime is hidden here
| the lifetime is hidden here
|
= help: the same lifetime is referred to in inconsistent ways, making the signature confusing
= note: `-D mismatched-lifetime-syntaxes` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(mismatched_lifetime_syntaxes)]`
help: use `'_` for type paths
|
125 | fn block_comment(input: Cursor<'_>) -> PResult<'_, &str> {
| ++++ +++
-----------------------------------------------------------------------
Follow the solution suggested by the compiler to silence the errors, for
all the observed occurrences.

This adds explicit lifetimes to any function which looks at a NIR
object, fishes a pointer out of it, and returns a reference. The theory
of operation for these NIR wrappers is that everything holds an implicit
shared reference to the whole shader and so this is safe to do as long
as no one ever has a mut reference to anything. However, since these
methods are turning pointers into references, it's a lot more obvious
what's going on if we have explicit lifetimes.
