error[E0621]: explicit lifetime required in the type of `is`
--> src/bee.rs:76:45

75 | fn compute_instruction_set<'a>(is: &'a mut InstructionSet) {
| ---------------------- help: add explicit lifetime `'a` to the type of `is`: `&'a mut [OpCode<'a>; 255]`
76 | let mut isb = InstructionSetBuilder{is: is, pos: 0};
| ^^ lifetime `'a` required
This is the code:
type InstructionSet<'a> = [OpCode<'a>; 0xff];
...
struct InstructionSetBuilder<'a> {
is: &'a mut [OpCode<'a>],
pos: usize,
}
...
fn compute_instruction_set<'a>(is: &'a mut InstructionSet) {
let mut isb = InstructionSetBuilder{is: is, pos: 0};
...
}
Why do I need to set yet another 'a lifetime param?
Where?
I tried several combinations, all broke the syntax...
type InstructionSet<'a> = [OpCode<'a>; 0xff];
This type alias is generic over a lifetime 'a. So you must specify it. Try this instead.
fn compute_instruction_set<'a>(is: &'a mut InstructionSet<'a>) {
let mut isb = InstructionSetBuilder{is: is, pos: 0};
...
}
