Trait DocPtr

pub trait DocPtr<'a, A>: Deref<Target = Doc<'a, Self, A>> + Sized
where
    A: 'a,
{
    type ColumnFn: Deref<Target = dyn Fn(usize) -> Self + 'a> + Clone + 'a;
    type WidthFn: Deref<Target = dyn Fn(isize) -> Self + 'a> + Clone + 'a;
}

Required Associated Types

type ColumnFn: Deref<Target = dyn Fn(usize) -> Self + 'a> + Clone + 'a

type WidthFn: Deref<Target = dyn Fn(isize) -> Self + 'a> + Clone + 'a

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.
