Enum TypeParam 

pub enum TypeParam<const N: usize> {}

Marker type specifying one of multiple type parameters to map over

The const generic N is the zero-based index of the type parameter, not counting lifetime parameters, but counting const generics.

For example, for a type Foo<'a, S, T>,

• TypeParam<0> refers to S and
• TypeParam<1> refers to T

and for a type Foo<'a, const N: usize, S, const M: usize, T>,

• TypeParam<1> refers to S and
• TypeParam<3> refers to T
