Trait QueryResult 

Source 
pub trait QueryResult {
    type Resolved<T>;

    // Required method
    fn map<T, F: FnMut(Key) -> T>(self, f: F) -> Self::Resolved<T>;
}
Expand description

Trait for types that can be returned from queries.

Required Associated Types§

Source

type Resolved<T>

Required Methods§

Source

fn map<T, F: FnMut(Key) -> T>(self, f: F) -> Self::Resolved<T>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
