Instead of setting a default value to a const and inside an
.unwrap_or_else closure, lets set it only to the const and reuse that
later in .unwrap_or
To achieve that we move the "unrwap_or" code for param plumbing code generation
a bit later so that we have easy access to the generated const name.
As all this code is related to optional/default-value stuff it does read still
relatively OK with that change, IMO.
This has the advantage of not getting a warning like:
> warning: constant is never used: `API_METHOD_EXAMPLE_FOO_PARAM_DEFAULT_FORCE`
> --> src/api2/node/foo.rs
> |
> XY | force: {
> | ^^^^^
> = note: `#[warn(dead_code)]` on by default
When one has a API endpoint like:
> #[api(
> input: {
> properties: {
> force: {
> type: bool,
> optional: true,
> default: false,
> },
> },
> },
> ...
> )]
> /// Example
> fn example_foo(force: bool) -> Result<(), Error> {
> if force {
> // do something
> }
> Ok(())
> }
It effectively changes the output for optional parameters with a default set
and no Option<T> from
> let p = p.unwrap_or_else(|| #default_value);
to
> let p = p.unwrap_or(#const_name_for_default);
where the "#const_name_for_default" is a pub const with value
"#default_value"
