Trait MapQuery 

pub trait MapQuery {
    type Query: ReadOnlyQueryData;
    type Output;

    // Required method
    fn map(data: <Self::Query as QueryData>::Item<'_, '_>) -> Self::Output;
}

A trait for types that can be constructed from query data.

See Get for more information on usage.

Required Associated Types

type Query: ReadOnlyQueryData

The query type which this type can be constructed from.

type Output

The output type that this query will map to.

Required Methods

fn map(data: <Self::Query as QueryData>::Item<'_, '_>) -> Self::Output

Called at the time of query execution to map the query data into Self.

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.
