[][src]Trait sp_runtime_interface::RIType

pub trait RIType {
    type FFIType: IntoValue + TryFromValue;
}

Something that can be used by the runtime interface as type to communicate between wasm and the host.

Every type that should be used in a runtime interface function signature needs to implement this trait.

Associated Types

type FFIType: IntoValue + TryFromValue[src]
