Trait FallibleLending 

pub trait FallibleLending<'lend, __ImplBound: ImplBound = Ref<'lend, Self>> {
    type Lend: 'lend;
}

The fallible counterpart of Lending. See its documentation for details on the HRTB implicit-bound technique used here.

Must be defined for any type that implements FallibleLender.

Required Associated Types

type Lend: 'lend
