error[E0425]: cannot find function `bar` in this scope
--> $DIR/non_valtreeable_const_arg-2.rs:11:16
|
LL | impl Wrapper<{ bar() }> {
| ^^^ not found in this scope
|
help: you might be missing a const parameter

LL | impl<const bar: /* Type */> Wrapper<{ bar() }> {

error: using function pointers as const generic parameters is forbidden
--> $DIR/non_valtreeable_const_arg-2.rs:8:25

LL | struct Wrapper<const F: fn()>;
| ^^^^

= note: the only supported types are integers, `bool`, and `char`
error[E0599]: the function or associated item `call` exists for struct `Wrapper<function>`, but its trait bounds were not satisfied
--> $DIR/non_valtreeable_const_arg-2.rs:17:26
|
LL | struct Wrapper<const F: fn()>;
| ----------------------------- function or associated item `call` not found for this struct because it doesn't satisfy `Wrapper<function>: Fn<_>`
...
LL | Wrapper::<function>::call;
| ^^^^ function or associated item cannot be called on `Wrapper<function>` due to unsatisfied trait bounds
|
= note: the following trait bounds were not satisfied:
`Wrapper<function>: Fn<_>`
which is required by `&Wrapper<function>: Fn<_>`
note: the trait `Fn` must be implemented
--> $SRC_DIR/core/src/ops/function.rs:LL:COL
= help: items from traits can only be used if the trait is implemented and in scope
= note: the following trait defines an item `call`, perhaps you need to implement it:
candidate #1: `Fn`
error: aborting due to 3 previous errors
Some errors have detailed explanations: E0425, E0599.
