Struct AnyOrNone 

pub struct AnyOrNone<A>(pub Option<A>);

Mainly used to generate types like (A, B)/() where OneOrNone would generate ((A, B))/(), but can also generate A/()

Tuple Fields

0: Option<A>

Trait Implementations

impl<A: FromMersData> FromMersData for AnyOrNone<A>

fn as_type_from() -> Type

fn can_represent(t: &Type) -> bool

fn try_represent<O, F: FnOnce(Option<Self>) -> O>( d: &(impl MersData + ?Sized), f: F, ) -> O

NOTE: f may only used the passed value of type Self during the call to f. Storing the value anywhere, moving it to a thread or otherwise assuming that it lives longer than the function call violates Rust’s lifetime rules, but is allowed by the compiler because of some unsafe code which calls f with a Self type with a lifetime that is incorrect on purpose (but seemingly necessary for this to work at all).
