Dyn Compatibility

This trait is not dyn compatible.

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

Implementors

impl<Context, L, R> HasPermission<Context> for And<L, R>

where Context: Sync, L: HasPermission<Context>, R: HasPermission<Context, Error = L::Error>,

type Error = <L as HasPermission<Context>>::Error

impl<Context, L, R> HasPermission<Context> for Or<L, R>

where Context: Sync, L: HasPermission<Context>, R: HasPermission<Context, Error = L::Error>,

type Error = <L as HasPermission<Context>>::Error
