Trait ReadVarValue

pub trait ReadVarValue {
    type Value;

    // Required method
    fn read_value(self, rt: &mut RustRuntimeServices<'_>) -> Self::Value;
}

Read the value of one or more flowey Vars.

By having this be a trait, it is possible to read both single instances of ReadVar / WriteVar, as well as whole collections of Vars.

Required Associated Types

type Value

The read value of Self.

Required Methods

fn read_value(self, rt: &mut RustRuntimeServices<'_>) -> Self::Value

Read the value of the Var at runtime.
