Trait ModuleDefLookup 

pub trait ModuleDefLookup:
    Sized
    + Debug
    + 'static {
    type Key<'a>: Debug + Copy;

    // Required methods
    fn key(&self) -> Self::Key<'_>;
    fn lookup<'a>(
        module_def: &'a ModuleDef,
        key: Self::Key<'_>,
    ) -> Option<&'a Self>;
}

Implemented by definitions stored in a ModuleDef. Allows looking definitions up in a ModuleDef, and across ModuleDefs during migrations.

Required Associated Types

type Key<'a>: Debug + Copy

A reference to a definition of this type within a module def. This reference should be portable across migrations.

Required Methods

fn key(&self) -> Self::Key<'_>

Get a reference to this definition.

fn lookup<'a>(module_def: &'a ModuleDef, key: Self::Key<'_>) -> Option<&'a Self>

Look up this entity in the module def.

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.
