Trait Query

pub trait Query: Copy {
    // Required methods
    fn setup(&self, context: &Context);
    fn get_query(&self) -> Vec<(TypeId, IndexValue)>;
}

Encapsulates a person query.

Context::query_people actually takes an instance of Query, but because we implement Query for tuples of up to size 20, that’s invisible to the caller. Do not use this trait directly.

Required Methods

fn setup(&self, context: &Context)

fn get_query(&self) -> Vec<(TypeId, IndexValue)>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
