Struct DeriveAndReportId

pub struct DeriveAndReportId<Params, ReportedId> {
    pub params: Params,
    /* private fields */
}

The DeriveAndReportId is an ID assignment approach intended to be used in "create" strategies.

It accepts the Params and the Id. The ReportedId value should be computed by the “create” strategy using the Params value.

The “create” strategy should report the ReportedId value upon successful asset creation.

An example of ID derivation is the creation of an NFT inside a collection using the collection ID as Params. The ReportedId in this case is the full ID of the NFT.

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

impl<Params, ReportedId> Encode for DeriveAndReportId<Params, ReportedId>

where Params: Encode, PhantomData<ReportedId>: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )
