Struct scones_examples::OverridableBuilt

pub struct OverridableBuilt {
    pub defaults_to_zero: i32,
}

An example showing how to use overrides in builders.

Overrides are sugar for accomplishing the job the OptionalBuilt example does with less verbosity. This example is defined as follows:

#[make_builder(pub OverridableBuilder(defaults_to_zero?))]
pub struct OverridableBuilt {
    #[value(0)]
    pub defaults_to_zero: i32,
}

The resulting builder will allow building this struct without specifying a value for defaults_to_zero, in which case zero will be used. At the same time, it allows a user of the builder to override that default, without you having to explicitly add a custom parameter, give it an Option<> type, and unwrap_or it in the #[value()] annotation.
