Struct CustomArgs

pub struct CustomArgs {
    pub product: i32,
    pub sum: i32,
}

An example showing how to add extra arguments to a constructor and use those arguments to initialize the existing fields.

It is defined as follows:

#[make_constructor(pub new(a: i32, b: i32))]
/// ^ Returns a new instance of `CustomArgs` with `product` equal to `a * b` and `sum` equal to
/// ^ `a + b`.
pub struct CustomArgs {
    #[value(a * b)]
    pub product: i32,
    #[value(a + b)]
    pub sum: i32,
}

Note that if the #[value()] annotations were ommitted for any field, the macro would add that field as an additional argument to the constructor automatically.

Fields

product: i32

sum: i32

Implementations

impl CustomArgs

pub fn new(a: i32, b: i32) -> Self

Returns a new instance of CustomArgs with product equal to a * b and sum equal to a + b.
