trait Value {}

impl<T> const Value for T {
    const fn value() -> u32 {
        0
    }

Error output

error[E0379]: functions in traits cannot be declared const
 --> treereduce.out:7:5
  |
7 |     const  fn value() -> u32 {
  |     ^^^^^ functions in traits cannot be const

error[E0407]: method `value` is not a member of trait `Value`
 --> treereduce.out:7:5
  |
7 | /     const  fn value() -> u32 {
8 | |         0
9 | |     }
  | |_____^ not a member of trait `Value`

error[E0601]: `main` function not found in crate `treereduce`
  --> treereduce.out:10:2
   |
10 | }
   |  ^ consider adding a `main` function to `treereduce.out`

error: const `impl` for trait `Value` which is not marked with `#[const_trait]`
 --> treereduce.out:6:15
  |
4 | trait Value {}
  | - help: mark `Value` as const: `#[const_trait]`
5 |
6 | impl<T> const Value for T {
  |               ^^^^^
  |
  = note: marking a trait with `#[const_trait]` ensures all default method bodies are `const`
  = note: adding a non-const method body in the future would be a breaking change
