Macro derive_deftly_template_AsMutSelf 

macro_rules! derive_deftly_template_AsMutSelf {
    ({ $($driver:tt)* } [$($aoptions:tt)*] ($($future:tt)*) $($tpassthrough:tt)*) => { ... };
    ($($wrong:tt)*) => { ... };
}

Implement AsMut<Self>

For Reasons, Rust does not have a blanket:

impl<T> AsMut<T> for T { .. }

This derive macro expands to the obvious and trivial implementation, for the type that it’s applied to.

This is a derive_deftly template. Do not invoke it directly. To use it, write: #[derive(Deftly)] #[derive_deftly(AsMutSelf)].
