Function init​

The Nft module initializer.

fun init(otw: nft::NFT, ctx: &mut tx_context::TxContext)
Implementation
fun init(otw: NFT, ctx: &mut TxContext) {
// Claim the module publisher.
let publisher = package::claim(otw, ctx);
// Build a Display object.
let keys = vector[
// The IOTA standard fields.
string::utf8(b"name"),
string::utf8(b"image_url"),
string::utf8(b"description"),
string::utf8(b"creator"),
// The extra IRC27-nested fields.
string::utf8(b"version"),
string::utf8(b"media_type"),
string::utf8(b"collection_name"),
// The issuer of the NFT. Equivalent to IRC-27 collectionId.
string::utf8(b"immutable_issuer"),
];
let values = vector[
// The IOTA standard fields.
string::utf8(b"{immutable_metadata.name}"),
string::utf8(b"{immutable_metadata.uri}"),
string::utf8(b"{immutable_metadata.description}"),
string::utf8(b"{immutable_metadata.issuer_name}"),
// The extra IRC27-nested fields.
string::utf8(b"{immutable_metadata.version}"),

string::utf8(b"{immutable_issuer}"),
];
let mut display = display::new_with_fields<Nft>(
&publisher,
keys,
values,
ctx
);
// Commit the first version of Display to apply changes.
display.update_version();
// Burn the publisher object.
package::burn_publisher(publisher);
// Freeze the display object.
iota::transfer::public_freeze_object(display);
}
