Implementors

impl ReadFromRow for Location

type Out = Value

TODO the whole point of the phantom data in AttributeMap is to disambiguate this type ... so that we can share the same value types in both directions of the database.

We don't have that here, so we need to modify the trait so that users can specify what kind of container things can be dumped into as long as it implements FromAffinityValue.

fn read_from_row(&self, c: &mut RowCursor<'_>) -> Result<Self::Out>

impl<'a, V> ReadFromRow for AttributeMap<'a, V> where
    V: FromAffinityValue, 

type Out = HashMap<&'a AttributeName<'a>, V>

fn read_from_row(&self, c: &mut RowCursor<'_>) -> Result<Self::Out>

impl<T, F> ReadFromRow for CrazyFuckingMemes<T, F> where
    F: ReadFromRow, 

type Out = <F as ReadFromRow>::Out

fn read_from_row(&self, c: &mut RowCursor<'_>) -> Result<Self::Out>
