Struct DisplayRegistry​

The root of display, to enable derivation of addresses.
The address is system-generated at 0xd

public struct DisplayRegistry has key
Click to open
Fields

Struct SystemMigrationCap​

A singleton capability object to enable migrating all V1 displays into V2.

public struct SystemMigrationCap has key

Fields

Struct Display​

This is the struct that holds the display values for a type T.

public struct Display<phantom T> has key
Click to open
Fields
id: sui::object::UID
fields: sui::vec_map::VecMap<std::string::String, std::string::String>
All the (key,value) entries for a given display object.
cap_id: std::option::Option<sui::object::ID>
The capability object ID. It's Option because legacy Displays will need claiming.

Struct DisplayCap​

The capability object that is used to manage the display.

public struct DisplayCap<phantom T> has key, store

Fields

Struct DisplayKey​

The key used for deriving the instance of Display.

public struct DisplayKey<phantom T> has copy, drop, store

Constants​

This is a multi-sig address responsible for the migration of V1 displays into V2.

Function new​

Create a new Display object for a given type T using internal::Permit to prove type ownership.

public fun new<T>(registry: &mut sui::display_registry::DisplayRegistry, _: std::internal::Permit<T>, ctx: &mut sui::tx_context::TxContext): (sui::display_registry::Display<T>, sui::display_registry::DisplayCap<T>)

Function new_with_publisher​

Create a new display object using the Publisher object.

public fun new_with_publisher<T>(registry: &mut sui::display_registry::DisplayRegistry, publisher: &mut sui::package::Publisher, ctx: &mut sui::tx_context::TxContext): (sui::display_registry::Display<T>, sui::display_registry::DisplayCap<T>)

Function unset​

Unset a key from display.

public fun unset<T>(display: &mut sui::display_registry::Display<T>, _: &sui::display_registry::DisplayCap<T>, name: std::string::String)

Function set​

Set a value for the specified key, replaces existing value if it exists.

public fun set<T>(display: &mut sui::display_registry::Display<T>, _: &sui::display_registry::DisplayCap<T>, name: std::string::String, value: std::string::String)

Function clear​

Clear the display vec_map, allowing a fresh re-creation of fields

public fun clear<T>(display: &mut sui::display_registry::Display<T>, _: &sui::display_registry::DisplayCap<T>)

Function share​

Share the Display object to finalize the creation.

public fun share<T>(display: sui::display_registry::Display<T>)

Function claim​

Allow a legacy Display holder to claim the capability object.

public fun claim<T: key>(display: &mut sui::display_registry::Display<T>, legacy: sui::display::Display<T>, ctx: &mut sui::tx_context::TxContext): sui::display_registry::DisplayCap<T>

Function claim_with_publisher​

Allow claiming a new display using Publisher as proof of ownership.

public fun claim_with_publisher<T: key>(display: &mut sui::display_registry::Display<T>, publisher: &mut sui::package::Publisher, ctx: &mut sui::tx_context::TxContext): sui::display_registry::DisplayCap<T>

Function system_migration​

Allow the SystemMigrationCap holder to create display objects with supplied values. The migration is performed once on launch of the DisplayRegistry, further migrations will have to be performed for each object, and will only be possible until legacy display methods are finally deprecated.

public fun system_migration<T: key>(registry: &mut sui::display_registry::DisplayRegistry, _: &sui::display_registry::SystemMigrationCap, keys: vector<std::string::String>, values: vector<std::string::String>, _ctx: &mut sui::tx_context::TxContext)

Function migrate_v1_to_v2​

Enables migrating legacy display into the new one, if a new one has not yet been created.

public fun migrate_v1_to_v2<T: key>(registry: &mut sui::display_registry::DisplayRegistry, legacy: sui::display::Display<T>, ctx: &mut sui::tx_context::TxContext): (sui::display_registry::Display<T>, sui::display_registry::DisplayCap<T>)

Function destroy_system_migration_cap​

Destroy the SystemMigrationCap after successfully migrating all V1 instances.

entry fun destroy_system_migration_cap(cap: sui::display_registry::SystemMigrationCap)

Function delete_legacy​

Allow deleting legacy display objects, as long as the cap has been claimed first.

public fun delete_legacy<T: key>(display: &sui::display_registry::Display<T>, legacy: sui::display::Display<T>)

Function fields​

Get a reference to the fields of display.

public fun fields<T>(display: &sui::display_registry::Display<T>): &sui::vec_map::VecMap<std::string::String, std::string::String>

Function cap_id​

Get the cap ID for the display.
