Derive Macro concordium_std::DeserialWithState

#[derive(DeserialWithState)]
{
    // Attributes available to this derive:
    #[concordium]
}

Derive the DeserialWithState trait. See the documentation of derive(Deserial) for details and limitations.

This trait should be derived for structs or enums that have fields with StateBox, StateSet, or StateMap. Please note that it is necessary to specify the generic parameter name for the HasStateApi generic parameter. To do so, use the #[concordium(state_parameter = "NameOfGenericParameter")] attribute on the type you are deriving DeserialWithState for.

Example

#[derive(DeserialWithState)]
#[concordium(state_parameter = "S")]
struct Foo<S, T> {
    a: StateMap<u8, u8, S>,
    #[concordium(size_length = 1)]
    b: String,
    c: Vec<T>,
}
