Trait mentat_db::types::TransactableValue

pub trait TransactableValue: Clone {
    fn into_typed_value(
        self, 
        schema: &Schema, 
        value_type: ValueType
    ) -> Result<TypedValue>;
    fn into_entity_place(self) -> Result<EntityPlace<Self>>;
    fn as_tempid(&self) -> Option<TempId>;
}

The transactor is tied to edn::ValueAndSpan right now, but in the future we'd like to support TypedValue directly for programmatic use. TransactableValue encapsulates the interface value types (i.e., values in the value place) need to support to be transacted.

Required Methods

fn into_typed_value(
    self,
    schema: &Schema,
    value_type: ValueType
) -> Result<TypedValue>

Coerce this value place into the given type. This is where we perform schema-aware coercion, for example coercing an integral value into a ref where appropriate.

fn into_entity_place(self) -> Result<EntityPlace<Self>>

Make an entity place out of this value place. This is where we limit values in nested maps to valid entity places.

fn as_tempid(&self) -> Option<TempId>
