A value of a particular cardinality (typically it’s provided automatically for T, Option<T>, Vec<T> or NonEmpty<T>)

Required Associated Constants

const EXPECTED_CARDINALITY: Cardinality

Required Methods

fn from_edgedb_set_value(value: Value) -> Result<Self>

fn interpret_possibly_missing_required_value(val: Option<Self>) -> Result<Self>

fn query_direct<Args: EdgedbQueryArgs + Send>( client: &Client, q: &str, args: Args, ) -> impl Future<Output = Result<Self>> + Send

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
