MultiplicitySelector

tor_netdoc::encode::multiplicity

Struct MultiplicitySelector 

Source 
pub struct MultiplicitySelector<Field>(PhantomData<fn(Field)>);
Expand description

Helper type that allows us to select an impl of MultiplicityMethods

For use by macros.

This is distinct from parse2::MultiplicitySelector, principally because it has the opposite variance.

Implementations§

Source§

impl<T> MultiplicitySelector<Vec<T>>

Source

pub fn selector(self) -> DeterminedMultiplicitySelector<Vec<T>>

Return the appropriate implementor of MultiplicityMethods

This is an inherent method so that it doesn’t need the EncodeOrd bounds: that way if EncodeOrd is not implemented, we get a message about that, rather than a complaint that ItemValueEncodable isn’t impl for Vec<T>.
