Struct tydi_intern::Id

pub struct Id<T> { /* fields omitted */ }

Intern Id

Used as wrapper when referencing interned values.

Examples

use tydi_intern::Id;

mod ast {
    use tydi_intern::Id;

    #[derive(Clone, Debug, PartialEq, Eq, Hash)]
    pub struct Root {
        // Instead of storing the full data for items we use the `Id`
        // wrapper
        pub items: Vec<Id<Item>>,
    }

    #[derive(Clone, Debug, PartialEq, Eq, Hash)]
    pub struct Item {
        pub identifier: String,
    }
}

#[salsa::query_group(InternStorage)]
pub trait Intern {
    #[salsa::interned]
    fn intern_item(&self, item: ast::Item) -> Id<ast::Item>;
}
