--> src/population.rs:95:11 | 95 | m:&'a Mutator, | ^^^^^^^ expected lifetime parameter
I can see a lifetime parameter, why can rustc not?
I realise I have not posted context but there is a lot of context. I am hoping that this is a common class of problem with a well known (not by me) procedure to debug it.
cargo explain E0106 does not help as it does not include the case where a life time parameter is both present and missing
If not I ill have to make a minimal case…
